HEADS UP

IBOLC at Fort Moore is 17 weeks. Your Ranger School slot — if you didn't get it as a cadet — is either embedded into your BOLC pipeline (RTAC + RS pre-PL) or held for after your first PL time, and which version you get materially shapes how your first battalion reads you. Ranger Tab is not officially required for an 11A in a line BCT, but the implicit math is real.

The Honest MOS Read
Second lieutenants in Infantry are the Army's load-bearing fiction: the Army runs on the work of platoon sergeants and squad leaders, but the institution gives the lieutenant the platoon and the OER and the implicit expectation that you'll figure out how to be useful inside 12 months. Your first KD (key developmental) job — Rifle Platoon Leader — is the only job in the entire 11A career field that you cannot recover from if you blow it. Battalion command at O-5, brigade command at O-6 — all of that traces back to whether your first BN CDR's OER on you as a rifle PL said "top block, future battalion commander" or "competent, time-served." The institutional memory is real. IBOLC (Infantry Basic Officer Leader Course) at Fort Moore (renamed from Fort Benning in 2023) is 17 weeks under the 199th Infantry Brigade. The course is tactically-dense — small unit tactics, platoon-level offense/defense, weapons, urban ops, patrolling — and it is fundamentally a graded performance assessment, not just instruction. Your IBOLC class ranking shapes (but does not formally control) your first-unit assignment. Ranger School integration varies by cohort: some IBOLC LTs get RTAC (Ranger Training Assessment Course) and a Ranger School slot before the first PL job; others get the slot held for after the first 12-18 months in the platoon. First-unit options: airborne (82nd ABN at Fort Liberty), air assault (101st at Fort Campbell), light (10th Mountain at Drum, 25th ID at Schofield, 173rd at Vicenza), Stryker (2nd Cav in Vilseck, 2/2 ID at JBLM, 1/25 ID at Wainwright, 3/2 ID at JBLM), or mechanized/armored (1st AD at Bliss, 1st CAV at Cavazos, 1st ID at Riley, 3rd ID at Stewart, 4th ID at Carson). The brigade type shapes everything about the next two years: light infantry rucks, Stryker is mounted-rotated, ABCT is Bradley-mounted with tankers next door. Volunteer airborne / air assault school slots are unit-allocated and visible career signals. The PL job itself: 30-40 soldiers, 1 platoon sergeant (E-7 SFC), 4 squad/section leaders (E-6 SSGs), and you. AR 600-100 and ADP 6-22 give you the doctrinal framework; the practical job is mission planning (OPORDs, troop-leading procedures), training management (long-range training calendar, ranges, FTXs), administrative leadership (counseling, NCOERs of your senior NCOs, soldier care), and the visible front of company-level operations. The platoon sergeant is your indispensable partner; lieutenants who try to be the SME in the squad room instead of the SME in the OPORD lose the platoon in week 2. The promotion math is structural under DOPMA. O-1 to O-2 is automatic at 18 months commissioned; O-2 to O-3 board at ~4 years commissioned with historically very high selection rates (>95% for fully-qualified competitive-zone officers per recent AR 600-8-29 board cycles — read your actual board's selection percentages, which HRC publishes). The competitive zone for Major (O-4) is roughly 10 years; that math becomes the conversation in your O-3 years. The ADSO math: ROTC and OCS commissions carry an 8-year service obligation under federal law and DA policy, generally 4 years AD + 4 years RC unless otherwise specified at commissioning. USMA commissions carry a 5-year AD service obligation. Branch detail (commissioning into one branch and detailing to another for KD time) is also a real path — read your commissioning packet carefully, the obligation length and structure varies.
Career Arc
  • 01Commission → IBOLC at Fort Moore (199th Infantry Brigade) — 17 weeks.
  • 02Ranger School slot — pre-PL (with RTAC) or post-PL hold, varies by cohort.
  • 03Airborne / Air Assault school slots — unit-allocated, career-visible.
  • 04First unit assignment: BCT type (IBCT / SBCT / ABCT / Airborne / Air Assault) shapes the next 24 months.
  • 05Rifle Platoon Leader — the load-bearing KD job. 12-18 months typical.
  • 06Company XO or specialty PL (Mortars, Scouts, AT, HHC) — second KD slot.
  • 07~Month 18: O-2 automatic. ~Month 48: O-3 board, historically very high selection.
Common Screwups
  • ×Trying to out-NCO your platoon sergeant. The PL job is to plan, resource, and command at platoon level — not to be the squad-room SME. SFCs who lose confidence in their LT report it.
  • ×Skipping Ranger School when offered. The Tab is not formally required but the implicit math is real: company commanders track who has it, the BN CDR's OER references it, and competitive selection downstream weights it.
  • ×DUI / Art 15 / unprofessional relationship — terminal for command consideration, separation risk under AR 600-20.
  • ×ACFT fails — flagging cascades through promotion, school slots, and KD assignment eligibility.
  • ×Treating the counseling cadence as bureaucracy. Initial counseling within 30 days of assumption, quarterly thereafter, and a clean DA 4856 paper trail is your legal defense and your OER input both.

A Day in the Life

  • 0500Wake. PT uniform on. Phone check — any platoon emergencies overnight? Soldier in jail, family deathgram, missed accountability formation, sensitive-item question from staff duty? The PSG hears about it as you walk into formation.
  • 0530PT formation. The PSG takes accountability of the platoon and reports to the company 1SG; you stand next to him and learn the cadence. After the first 90 days you take accountability yourself with the PSG behind you.
  • 0545-0700Unit PT. You run the platoon's plan within the company's plan. Mondays / Wednesdays / Fridays are typically cardio / interval; Tuesdays / Thursdays are strength or sandbag / ruck cycles. You do PT with the platoon — the LT who skips PT is the LT the squad room talks about within a cycle.
  • 0700-0900Hygiene, breakfast, change uniforms. You spend 30-45 minutes reading the day's training schedule, the company training meeting notes, and any S-3 tasker from the BUB. Coffee with the PSG; you align on the day before first formation.
  • 0900First formation. The 1SG addresses the company; the PSG translates company tasks to the platoon; you stand behind him and pick up squad-level adjustments. After 90 days you address the platoon when there is a platoon-specific item.
  • 0915-1130Platoon-level work. You may be at the BN S-3 working a training calendar input, at the brigade range control coordinating a range packet, at the company orderly room signing for serialized gear, at the arms room doing a sensitive-item layout, or in the CO's office reviewing the company OPORD for the next FTX. Counseling appointments with squad leaders or specialists land in this window.
  • 1130-1300Chow. You eat with the other LTs in the company. The conversation drifts to school slots, OER support-form discipline, branch detail (if applicable), and which BCT CDR is signing what kind of senior rater comments this cycle.
  • 1300-1500Afternoon work. OPORD drafting for the next training event. NCOER input on your specialists and below through the PSG; OER support form drafting on the PSG (you write it; the CO and BN CDR rate it). Counseling cycle catch-up — quarterly counseling on the SSGs, monthly developmental counseling on the PSG.
  • 1500-1630Final formation. PSG briefs the platoon on the day's wrap-up; you brief any platoon-specific items. Sensitive-items count by squad — weapons, NVGs, radios, crypto, optics. Walk the line with the PSG on critical end items.
  • 1630-1730Platoon release. You stay 30-45 minutes with the PSG — quick AAR on what worked, what did not, what to adjust tomorrow. The LT who closes out the day with the PSG is the LT whose CO is never surprised at the next training meeting.
  • 1730-2000Personal time. Married LTs: family. Single LTs: gym, study, school packet build if Ranger or Airborne is in the pipeline, doctrine reading on your own time. The LT who reads ATP 3-21.8 and FM 3-21.10 cover-to-cover during the first six months as a PL is the LT whose OPORDs do not need CO rewrites.
  • 2000-2200Counseling drafting if a DA 4856 is owed today. OPORD revision for tomorrow's back-brief. If you are 12-18 months from the post-PL KD slate, you are reading the assignment officer's slate guidance and building the OER support-form narrative your senior rater can defend.
  • 2200Lights out.
  • Field rotation / CTC train-upThe clock collapses. You are running the platoon as the senior officer on the ground (the CO floats between platoons). Sleep in 2-3 hour blocks. The CTC rotation as a PL is the brigade's most-observed moment of your tier — perform here or the post-PL utilization slate quietly narrows.

Weekly Cadence

The Mon-Fri rhythm at the rifle PL level is the platoon-leader version of the company commander's rhythm. Monday is the heaviest planning day — you read the company training meeting notes from Friday, adjust the platoon's plan to match the company tasking, and brief the PSG and squad leaders by mid-morning. The OPORD for the week's primary training event lands in draft by Tuesday morning; you back-brief the CO by Tuesday afternoon; FRAGOs come out Wednesday if the BN S-3 calendar shifts. Tuesday and Wednesday are the platoon's primary training days — STT, lane validations, gunnery prep, ranges, FTX preparation. The PSG runs squad-level execution; you run platoon-level command and the integration with the CO. Thursday is usually maintenance, motor pool, or company-level prep; Friday is the company training meeting and the weekend release. The week's QTB / OER / counseling / school-packet work happens in the gaps — usually Tuesday afternoon, Thursday afternoon, and the evening hours. The week's second rhythm is the OER / school / branch-management cycle. OER support forms are owed quarterly to the rater and senior rater. School packets (Ranger, Airborne, Air Assault, Pathfinder, Mountain Warfare) have 3-9 month lead times through the BN S-3 and ATRRS. The branch manager (the HRC Infantry assignments officer for company-grade officers) is the LT's lifeline for the post-PL utilization slate — the LT who reaches out at the 12-month mark with a clean record and named preferences is the LT who gets the assignment slate he wanted. The LT who waits for the slate to find him is the LT whose post-PL job is whatever was left. The week's third rhythm is the personal development cycle. Doctrine reading on your own time — ATP 3-21.8, FM 3-21.10, ADP 3-90, ADP 3-21, ADP 6-22 — through the first 18 months as a PL. ACFT maintenance year-round (the test the platoon has to pass). Tab and badge consolidation — Ranger, Airborne, Air Assault, EIB if you didn't get it as a cadet — across the first 24 months. The LT who builds the doctrine + tab + ACFT + OER stack across the LT tier is the LT whose company command slate at O-3 is a real conversation.

Key Skills — How to Drill Each

  1. 01
    Brief a five-paragraph platoon OPORD in front of the company commander that he does not have to rewrite.
    Ranger Handbook five-paragraph format — situation, mission, execution, sustainment, command and signal. Graphics on a 1:50K or 1:25K with phase lines, objectives, axes of advance, control measures. Build it the way IBOLC small-group leaders taught you: WARNO out within an hour of receipt of mission, OPORD back-brief 24 hours before execution, FRAGOs written (not just radioed) when the plan changes. The CO who reads a clean PL OPORD signs it; the CO who rewrites your OPORD is the CO whose senior rater comment on you reads 'requires guidance to produce staff-level product.'
  2. 02
    Run troop-leading procedures (TLP) end-to-end per ADP 5-0 / FM 6-0 — and never cut the rehearsal step.
    TLP is the eight-step LT spine: receive the mission, issue WARNO, make a tentative plan, initiate movement, conduct recon, complete the plan, issue OPORD, supervise and refine. The step LTs cut first is step 8 — supervision and rehearsal — because the calendar is tight and the soldiers are tired. Don't. The BN CDR reads the platoon's reaction-to-contact in the next CTC lane as the test of whether you rehearsed. Walk the rehearsal on a sand table or terrain model with every squad leader and the PSG present; back-brief from squad up; never assume the platoon understood the plan because you briefed it once.
  3. 03
    Apply METT-TC as the planning framework you actually use, not a checkbox in the OPORD.
    Mission, enemy, terrain and weather, troops and support available, time available, civil considerations. METT-TC drives every PL decision from route selection to attack-position placement to MEDEVAC posture. Build the habit: when the CO hands you the company OPORD, your first 30 minutes are METT-TC notes on the back of the order, not PowerPoint. The LT who plans from METT-TC is the LT whose plan survives contact; the LT who plans from a template is the LT whose plan dies on the LD.
  4. 04
    Sign for the platoon's sensitive items and never lose accountability — not for a minute, not for one cycle.
    Property book responsibility runs through AR 735-5 and DA PAM 710-2-1. Sensitive items — weapons, NVGs (PVS-14, ENVG-B), radios (PRC-117G, PRC-152, PRC-163), crypto, optics, designators — get serial-number accountability at every transition: morning formation, range departure, range return, field departure, field return, end of day. Run a sensitive-item layout monthly with the PSG. A missing serial number is a 15-6 with your name in the findings; the BCT CDR signs the 15-6 outbrief, and the comment lives in your file.
  5. 05
    Build a platoon training plan that gets resourced through the company training meeting and survives the brigade QTB.
    The Quarterly Training Brief is the brigade's resource-allocation forum where the BN CO and CSM defend the training plan. Your input rolls up through the CO and PSG; it has to be METL-aligned, ammunition-realistic, range-realistic, and time-realistic. Build the plan with the PSG before you brief the CO; align it with the company METL the CO published; pull the 8-step training model out of AR 350-1 and walk through it. The platoon whose training plan gets resourced is the platoon whose PL wrote the most defensible slide.
  6. 06
    Read the platoon sergeant the way the platoon sergeant reads you — listen first, push back in private, never undercut in public.
    The SFC has 15+ years in the squad room; you have 17 weeks. The relationship is the load-bearing structural element of the platoon. Listen first when he speaks; never reverse him in front of the squad leaders; take disagreements to the office and walk out aligned. Initial counseling within 30 days of assumption — DA 4856, signed, filed. Quarterly counseling thereafter. The PSG who trusts the LT is the PSG who tells the LT what the soldiers really think; the PSG who does not trust the LT routes around him to the CO.

Manuals & References — What Chapters Matter

  • ADP 3-90 — Offense and Defense; ADP 3-21 — Infantry Operations.
    The conceptual spine of every platoon-level mission you will plan. ADP 3-90 frames the offense / defense at the doctrinal level; ADP 3-21 is the infantry-specific operational umbrella. Read both in your first 60 days as a PL — the BN CDR quotes from both at the BUB, and the LT who can frame a platoon plan in doctrinal language is the LT the CO trusts to brief at battalion.
  • FM 3-21.10 — Infantry Rifle Company; FM / ATP 3-21.8 — Infantry Platoon and Squad.
    ATP 3-21.8 is the platoon-and-squad bible — read chapters on offense, defense, patrolling, and stability before your first FTX. FM 3-21.10 is the company-level reference the CO is working from; reading it tells you where your platoon fits in the company scheme of maneuver and lets you anticipate the CO's intent without him explaining it three times.
  • ADP 6-22 — Army Leadership and the Profession; AR 600-100 — Army Profession and Leadership Policy.
    ADP 6-22 is the leadership-doctrine umbrella; AR 600-100 codifies the Army Profession framework. The OER support form language the senior rater writes comes from these documents. The LT who reads them once a quarter is the LT whose self-assessment and rater-input narratives align with what the senior rater can actually defend.
  • AR 600-20 — Army Command Policy.
    SHARP, EO, unprofessional relationships, command authority, the chain of command — the policy you enforce inside the platoon and the policy you can end your career on if you violate. Re-read annually; the reg changes. Initial SHARP / EO training the day you assume the platoon — documented, signed, filed.
  • AR 623-3 + DA PAM 623-3 — Evaluation Reporting System.
    The OER reg — read both before your first rater-ratee touchpoint. AR 623-3 is the source doctrine; DA PAM 623-3 is the procedural detail (DA 67-10 series forms, senior rater profile management, top block / center of mass mechanics). You also rate your platoon sergeant — your NCOER on him is the document the centralized E-7 board reads.
  • DA PAM 600-3 — Officer Professional Development; AR 350-1 — Army Training and Leader Development.
    DA PAM 600-3 chapter on the Infantry branch describes the KD timing windows, the FA designation conversation that lands at O-3, the typical career arc through battalion command and beyond. AR 350-1 governs training-event approval, the 8-step training model, range certification — the framework your QTB input rolls up against.

Standards — How to Hit Each

  • IBOLC graduate — 17 weeks at Fort Moore (renamed from Fort Benning in 2023) under the 199th Infantry Brigade.
    IBOLC is the Infantry's accession course at the Maneuver Center of Excellence. Class standing is not formally slated but the read travels with you to the first BCT. Treat the small-unit tactics phase, the patrolling phase, the urban-ops phase, and the live-fire phase as graded performance — the small-group leaders write narrative comments that informal back-channel into your branch manager. The LT who graduates IBOLC with a strong tactical read arrives at the first BCT with momentum the BN CDR will notice.
  • Ranger School slot — pre-PL with RTAC integrated, or post-PL hold. Not formally required for an 11A in a line BCT, but the implicit math is real.
    Some IBOLC cohorts get RTAC (Ranger Training Assessment Course) and a Ranger School slot embedded into the pipeline; others get the slot held for after the first 12-18 months in the platoon. RTAC is the pre-Ranger gate — pass it, the slot opens. Pass Ranger School, the Tab opens every door downstream: company command slate competitiveness, branch slating reads, OER bullet weight. The LT who declines the slot when offered or fails the gate without a recycle plan is the LT whose first BN CDR's OER quietly notes the gap.
  • Airborne / Air Assault / Pathfinder / Mountain Warfare slot — unit-allocated, career-visible.
    These slots are command-allocated through the BN S-3 and BCT S-3. Volunteer early; the LT who is on the school request roster from week one is the LT who gets the slot when it opens. Airborne (3 weeks at Fort Moore), Air Assault (10-12 days at Fort Campbell or unit-resident), Pathfinder (3 weeks at Fort Moore), Mountain Warfare (Vermont National Guard, 14 days summer / 12 days winter). The patch / badge stack is the visible differentiator the CO reads at the next OER cycle.
  • ACFT 540+ floor, 580+ if pushing for Ranger or specialty schools.
    ACFT (Army Combat Fitness Test) is the six-event assessment — MDL, SPT, HRP, SDC, PLK, 2MR. 540 is the LT floor that keeps you out of trouble; 580+ is the realistic bar for Ranger / Sapper / SF assessment. Build the platoon's PT program around the platoon's weakest soldier's deficit; your platoon's aggregate ACFT pass rate is the company-level slide the CO reads at the BUB. The LT who fails the test the platoon has to pass loses standing with the squad room within a cycle.
  • DOPMA promotion math: O-1 to O-2 automatic at 18 months; O-2 to O-3 board at ~4 years.
    O-1 to O-2 is automatic at 18 months commissioned under AR 600-8-29 and DOPMA — no board action required. O-2 to O-3 is a board at roughly 4 years commissioned with historically very high select rates for fully-qualified competitive-zone officers. Pull the current HRC officer promotion board release for the FY-specific selection percentage; do not assume from rumored numbers. The ADSO clock: 8-year total obligation for ROTC and OCS commissions (typically 4 AD + 4 RC unless branch-detailed or otherwise specified); 5-year AD ADSO for USMA. Branch-detail and additional-school ADSOs stack on top.

Technical Mistakes — Concrete Consequences

  • Cutting the rehearsal step in TLP.
    You get away with it once. The second time, the company commander watches your platoon fail react-to-contact in a CTC lane and your OER support-form bullets get rewritten on the spot. The O/C/T at JRTC or NTC writes the takehome AAR; the AAR follows your file the rest of your career; the next BN CDR who reads it knows you were the PL who skipped step 8.
  • Losing accountability of a sensitive item — weapon, NVG, radio, crypto — even for an hour.
    As the LT signing the property book, one serial number unaccounted for triggers AR 15-6 investigation under AR 735-5. The BCT CDR signs the 15-6 outbrief and the comment lives in your file. The 15-6 finding can recommend Financial Liability Investigation of Property Loss (FLIPL) against you personally for the value of the missing item. The CO who supported you at the start of the investigation cannot defend the OER comment after; the brigade staff sees your name on the 15-6 distribution before the OER hits the senior rater's desk.
  • Bypassing the PSG to talk directly with squad leaders, or undercutting him in front of the platoon.
    The SFC routes around you to the 1SG within a week. The 1SG calls the CO; the CO has the conversation with you; the OER support-form language shifts from 'building strong NCO partnership' to 'requires development in officer-NCO relationship.' The PSG who does not trust the LT is the PSG who tells the platoon to wait for the CO's guidance instead of the LT's, and the platoon notices inside two formations.
  • Briefing an OPORD with bad graphics or missing control measures.
    The CO refuses to sign the OPORD or rewrites it overnight. Your platoon executes off a CO-edited plan that does not match the brief you gave the squad leaders. Squads collide on the objective or miss the LD time because your graphics had no phase lines. The lane evaluator at the next FTX writes the platoon's performance against the standard, and the OPORD discipline failure is what the AAR opens with.
  • Posting OPSEC-relevant content on social media — unit patch, training location, weapon serial, soldier name in a deployment photo.
    The BCT S-2 spots it during a routine OPSEC scan. The collection effort against US formations is real — adversary services aggregate social media content for order of battle, deployment timing, and personnel identification. The S-2 reports up to the BCT CDR; the BCT CDR's first conversation with you is not the one you wanted as a new LT. AR 530-1 (Operations Security) violations at LT are recoverable but visible; repeats are career-shaping.

Career Decisions at This Rank

  • Branch detail vs. branch of accession — the commissioning-level fork.
    Branch detail (commissioning into one branch and detailing to another for the LT KD cycle) is a real path for some 11A officers; the most common version is 11A commissioning with a detail into a sister combat-arms branch (Armor / Cavalry / Field Artillery) for the LT tier, then returning to 11A at company-grade. Read your commissioning packet carefully — the obligation length and the structure of the detail affects the ADSO clock, the post-LT utilization slate, and the company command slate downstream. The decision is largely made at commissioning; the question at LT is how you execute inside the structure you were given.
  • Ranger School timing — pre-PL with RTAC, or post-PL hold.
    Some IBOLC cohorts get RTAC and a Ranger slot embedded into the pipeline; others get the slot held for after 12-18 months in the platoon. The pre-PL version means you arrive at the first BCT with the Tab and the credibility; the post-PL version means you build PL competence first and absorb the school's physical and tactical demand with more rep under your belt. The decision is usually made for you by the cohort math, but if you have any input — express preference early through IBOLC cadre and the gaining BN S-3. The LT who declines the slot when offered is the LT whose first BN CDR's OER quietly notes the gap.
  • Post-PL KD slot — Company XO, specialty PL (Mortars, Scouts, AT, HHC), or BN staff.
    After 12-18 months as Rifle PL, the second LT KD lands. Company XO (executive officer, the 1LT seat running company-level logistics, property book, and the CO's right hand) is the most common follow-on and the most operationally formative. Specialty PL slots — Mortar Platoon Leader, Scout Platoon Leader, Anti-Tank Platoon Leader, HHC PL — are technical alternates that build a different OER narrative. BN staff at LT is less common but happens when the BN S-3 or S-4 needs an officer. The decision is largely the BN CDR's; your input matters at the 9-12 month mark. Volunteer for Company XO if you want the broadest preparation for company command; volunteer for Scout / Mortar PL if you want the specialty depth.
  • Volunteer airborne / air assault / specialty schools — when and how aggressively.
    Airborne (Fort Moore, 3 weeks), Air Assault (Fort Campbell or unit-resident, 10-12 days), Pathfinder (Fort Moore, 3 weeks), Mountain Warfare (Vermont NG, summer / winter cycles). These slots are unit-allocated through the BN S-3 and BCT S-3; volunteer early — the LT on the school request roster from week one is the LT who gets the slot. The decision is whether to push for the slot in the first PL year (builds the patch / badge stack early, costs platoon time) or in the post-PL window (preserves PL time but compresses the school slate against post-LT utilization). Most successful 11A LTs took at least one specialty school during the LT tier.
  • Functional Area conversation (the early read).
    Functional Area designation lands at O-3 (~7-8 years commissioned), not at LT. But the conversation begins earlier — your post-LT utilization tour, your specialty schools, your educational background, and your career interests all shape which FAs your branch manager will name when designation comes up. The decision at LT is to start the conversation: read DA PAM 600-3 chapter on the Infantry branch, read the FA-specific entries on FA40 Space, FA47 USMA Permanent Faculty, FA48 FAO, FA49 ORSA, FA50 Force Management, FA51 Acquisition, FA52 Nuclear/CWMD, FA53 IT, FA57 Simulations, FA59 Strategist. The LT who arrives at the FA designation window with a thought-out preference is the captain who gets the FA that shapes the next decade. The LT who arrives with no preference gets the FA HRC needs to fill.

How the Seat Varies by Unit Type

  • Light Infantry PL (10th MTN at Drum, 25th ID at Schofield, 173rd at Vicenza, 11th AB at Wainwright)
    The light infantry PL runs a 30-40 soldier dismounted platoon. JRTC at Fort Johnson (renamed from Fort Polk in 2023) is the home rotation. The community values the tab / badge stack heavily — Ranger, Air Assault, Airborne (if airborne-coded), EIB. The 10th Mountain and 25th ID emphasize light-fighter movement and rucking; the 173rd Airborne Brigade Combat Team has the European theater rotation cycle through JMRC at Hohenfels.
  • Airborne PL (82nd ABN at Fort Liberty — renamed from Fort Bragg in 2023)
    The 82nd ABN PL runs a 30-40 soldier airborne-qualified platoon. Airborne School is the entry credential; the platoon does proficiency jumps regularly and conducts airborne operations in training and contingency response. The 82nd is the immediate-response force component of the Global Response Force (GRF) — the OPTEMPO is the GRF rotational readiness model. The community reads heavily on tab / badge stack and the visible commitment to the airborne identity.
  • Air Assault PL (101st AAB at Fort Campbell)
    The 101st Airborne Division (Air Assault) PL runs a 30-40 soldier air-assault-qualified platoon. Air Assault School (Fort Campbell, 10-12 days resident) is the entry credential. The 101st operates as the Army's premier air-assault formation — the platoon trains for rotary-wing insertion, sling-load operations, and air-assault tactics. The OPTEMPO and the helicopter-centric integration with the 101st Combat Aviation Brigade make this seat materially different from light infantry.
  • Stryker PL (2nd CR Vilseck, 2/2 ID JBLM, 1/25 ID Wainwright, 3/2 ID JBLM)
    The Stryker PL runs a 30-40 soldier platoon that splits between mounted (ICV crew operations) and dismounted (rifle team operations). The ICV (Infantry Carrier Vehicle) and its variants drive the maintenance cycle, the gunnery table progression (Strykers run their own gunnery tables), and the tactical scheme. The platoon SOP is hybrid mounted-dismounted; the PL who masters the integration is the PL the CO trusts on the most demanding tasks. JRTC and NTC are the home rotations.
  • Mechanized / Armored Infantry PL (1AD Bliss, 1CAV Cavazos — renamed from Fort Hood in 2023, 1ID Riley, 3ID Stewart, 4ID Carson)
    The ABCT (Armored Brigade Combat Team) mechanized infantry PL runs a Bradley-mounted platoon — 4 Bradley fighting vehicles, 4 dismounted rifle squads, 30-40 soldiers total. The Bradley gunnery tables (Tables VII-XII) and the integration with the ABCT's tank battalions drive the training cycle. NTC at Fort Irwin is the home rotation. The Bradley Master Gunner course at Fort Moore is the technical credential the BC reads; the platoon's gunnery scores are the brigade-level metric the BCT CDR sees every quarter.

What Good Looks Like at This Rank

The good rifle PL is the LT the company commander sends to brief the BN CDR without rehearsing the brief first. His OPORDs do not get rewritten by the CO. His platoon sergeant trusts him enough to push back honestly in private and align publicly. By his second OER cycle he has a Ranger Tab (if the slot existed for his cohort), a clean property book that survived a sensitive-item layout the BCT CSM ran without notice, and a platoon with the strongest collective lane scores in the company. His senior rater profile reads "top block, future battalion commander" — the language the O-3 board reads at the rubber-stamp moment, but more importantly the language the BCT CDR remembers when slating into company XO and the post-LT staff utilization tour. His TLP discipline is visible. He WARNOs within an hour of receipt of mission, rehearses on a sand table or terrain model with every squad leader present, back-briefs from squad up, and never assumes the platoon understood the plan because he briefed it once. His sensitive-item accountability is automatic — morning formation, range departure, range return, field departure, field return, end of day — and his PSG does the random monthly layout because the SFC and the LT built the cadence together. His counseling cadence is clean: initial within 30 days, quarterly thereafter, event-driven when warranted, every DA 4856 filed in the platoon's training folder where the IG can find it if they ever need to. The LT who is being groomed for branch slate competitiveness looks different from the LT who is comfortable as a PL. The grooming LT volunteers for the hardest tasks, builds a tab-and-badge stack early, and reads doctrine on his own time — not because IBOLC told him to but because the OPORD he writes Tuesday morning has to defend itself in the BN BUB Tuesday afternoon. The comfortable LT pins O-2 at the 18-month mark and pins O-3 at the 4-year mark and stops being noticed by the BN CDR. The slating math at company command (which lands ~6-8 years commissioned) reads the cumulative LT-tier OER profile heavily — the LT who built the profile is the captain who gets the company command slot he wants.

Preview — The Next Rank

O-3 (Captain) is the rank where the Army decides what kind of officer you actually are. The visible pipeline runs: post-LT KD (BN S-1, S-4, AS3, or BCT staff slot) → MCCC (Maneuver Captains Career Course at Fort Moore, ~22 weeks under the 199th Infantry Brigade and the MCoE) → company command (rifle, weapons, HHC, or specialty — 18-24 months under AR 600-20). Company command is the single OER block that the O-4, O-5, and O-6 boards care about with the same intensity that the rifle PL OER mattered at LT. The CTC rotation you run as a company commander is the most-observed performance window of your career to date; the O/C/Ts writing the takehome AAR are senior captains and majors at observer / coach / trainer billets and the AAR culture means the visibility is real. The Functional Area designation at ~7-8 years commissioned (FA40 Space, FA47 USMA Faculty, FA48 FAO, FA49 ORSA, FA50 Force Management, FA51 Acquisition, FA52 Nuclear/CWMD, FA53 IT, FA57 Simulations, FA59 Strategist) shapes the O-5 and O-6 utilization path in non-line tracks. The dual-track happens silently in the background of company command time; the FA you designate into shapes which colonel-track doors stay open. The O-4 board math is no longer a rubber-stamp — pull the most recent HRC officer promotion board release for the current FY rate. The IPZ window runs roughly 9-10 years commissioned with 3-4 years TIG. The LT-tier OER profile you built across the rifle PL year and the post-PL KD slot is the foundation under everything that follows. The captain who got slated into the company command he wanted is the captain whose senior rater profile across the LT tier read "top block, future battalion commander." The captain who did not is the captain whose company command slate was a smaller conversation and whose post-command utilization tour was thinner. Build the profile at LT or the math is harder at every board downstream.
FAQ

11A O1-O2 — Frequently Asked Questions

Q01What does a O1-O2 11A (Infantry) actually do?
You commission, get sent to IBOLC (Infantry Basic Officer Leader Course) at Fort Moore (renamed from Fort Benning in 2023) — 17 weeks under the 199th Infantry Brigade and the Maneuver Center of Excellence — and then hit your first BCT as a brand-new rifle PL.
Q02What's the most important thing to know as a O1-O2 11A?
IBOLC at Fort Moore is 17 weeks.
Q03What does a typical day look like for a O1-O2 11A?
Time-blocked day at the O1-O2 11A rank tier: 0500 Wake. PT uniform on. Phone check — any platoon emergencies overnight? Soldier in jail, family deathgram, missed accountability formation, sensitive-item question from staff duty? The PSG hears about it as you walk into formation, 0530 PT formation. The PSG takes accountability of the platoon and reports to the company 1SG; you stand next to him and learn the cadence. After the first 90 days you take accountability yourself with the PSG behind you, 0545-0700 Unit PT. You run the platoon's plan within the company's plan.…
Q04What mistakes get O1-O2 11A soldiers fired or relieved?
Trying to out-NCO your platoon sergeant. The PL job is to plan, resource, and command at platoon level — not to be the squad-room SME. SFCs who lose confidence in their LT report it; Skipping Ranger School when offered. The Tab is not formally required but the implicit math is real: company commanders track who has it, the BN CDR's OER references it, and competitive selection downstream weights it; DUI / Art 15 / unprofessional relationship — terminal for command consideration,…
Q05What career decisions matter most at the O1-O2 11A rank tier?
Branch detail vs. branch of accession — the commissioning-level fork — Branch detail (commissioning into one branch and detailing to another for the LT KD cycle) is a real path for some 11A officers; the most common version is 11A commissioning with a detail into a sister combat-arms branch (Armor / Cavalry / Field Artillery) for the LT tier, then returning to 11A at company-grade. Read your commissioning packet carefully — the obligation length and the structure of the detail affects the ADSO clock, the post-LT utilization slate, and the company command slate downstream.…
Q06What's next after O1-O2 for a 11A (Infantry) in the Army?
O-3 (Captain) is the rank where the Army decides what kind of officer you actually are.
Q07What manuals and regulations does a O1-O2 11A need to know cold?
ADP 3-90 — Offense and Defense; ADP 3-21 — Infantry Operations (the conceptual spine of every platoon mission you will plan).; FM 3-21.10 — Infantry Rifle Company; FM 3-21.8 / ATP 3-21.8 — Infantry Platoon and Squad (the manuals your CO and platoon sergeant both quote from).; ADP 6-22 — Army Leadership and the Profession; AR 600-100 — Army Profession and Leadership Policy.
