Infantryman

E-1 to E-3 (Junior Enlisted) · Army

E1–E3E-4E-5E-6E-7E8–E9
HEADS UP

OSUT at Fort Moore is 22 weeks — that's BCT and Infantry AIT in one continuous block. You don't get to go home between phases. The first unit you hit after graduation will read your DA Form 1059 (academic eval) and your end-of-cycle counseling; both follow you to your gaining battalion.

The Honest MOS Read
You enlisted, signed for 11B, and you're either heading to or just left 22-week One Station Unit Training at Fort Moore, GA (the post the Army renamed from Fort Benning in 2023). OSUT is run by the 198th Infantry Brigade, and it is structurally different from the split BCT-then-AIT model most other MOSes follow: you stay with the same drill sergeants and same cohort for the entire 22 weeks. That has good and bad implications. Good: the cadre knows you. They know whether you're the squad leader-in-waiting or the recovery project. Bad: if you start poorly in week 3, you live with that read for the next 19 weeks unless you can visibly course-correct. Pin-on at Fort Moore is your end of OSUT, and you'll PCS to your gaining unit as a PV2 or PFC depending on enlistment-credit. Promotion to E-2 is automatic at 6 months TIS under AR 600-8-19; E-3 is automatic at 12 months TIS with 4 months TIG (waivable to 6 mo TIS / 2 mo TIG). E-4 is the real first promotion gate — it requires 24 months TIS / 6 months TIG (both waivable), and starts looking at the command, not just the clock. Your gaining unit determines almost everything about your first three years. The Infantry lives in three different worlds: Infantry Brigade Combat Teams (IBCT, light infantry — 82nd ABN, 101st, 10th Mountain, 25th ID, 173rd), Stryker Brigade Combat Teams (SBCT — 2nd Cav in Germany, 2/2 ID at JBLM, 1/25 ID in Alaska, 3/2 ID at JBLM), and Armored Brigade Combat Teams (ABCT — 1st AD at Bliss, 1st CAV at Hood/Cavazos, 1st ID at Riley, 3rd ID at Stewart, 4th ID at Carson). These are not interchangeable jobs. Light Infantry rucks. Stryker has IFVs and a different tactical rhythm. Armored Infantry rides in Bradleys and lives next door to tankers. The recruiter probably did not explain that the slot is assigned in the back half of OSUT and depends on the needs of the Army, not your preferences. Combat Training Center rotations are the institutional rhythm. NTC at Fort Irwin (desert, decisive-action force-on-force) and JRTC at Fort Johnson (renamed from Fort Polk in 2023, jungle/woodland, light infantry-centric) cycle BCTs through 2-3 week rotations roughly every 18-24 months in the readiness model. Your battalion's CTC rotation will be the most informationally-dense event of your first enlistment — and the place where everyone above E-4 figures out who you actually are when you're tired. The pay piece nobody briefs hard enough: BRS (Blended Retirement System) is the default for everyone enlisted after Jan 2018. You get an automatic 1% government TSP match and a 4% match if you contribute 5%. Most E-1s do not max this. The math of starting at 19 with 5% in TSP vs starting at 26 is genuinely life-altering. Talk to S-1 about your TSP contribution in your first week at your unit, not your second year.
Career Arc
  • 01OSUT at Fort Moore (198th Infantry Brigade) — 22 weeks combined BCT + Infantry AIT, single cadre throughout.
  • 02PCS to gaining unit (IBCT, SBCT, or ABCT) — slot assigned in back half of OSUT.
  • 03Reception, in-processing, RSP (Reception, Staging, Onward Movement) — your first NCOER counseling cycle begins.
  • 04Month ~6 TIS: E-2 (automatic per AR 600-8-19).
  • 05Month ~12 TIS: E-3 / PFC (4 mo TIG, waivable to 6/2).
  • 06First gunnery / live fire / squad STX rotation — your section sergeant's read of you forms here.
  • 07First CTC rotation (NTC/JRTC) within 18-24 months at unit — the rotation BCT readiness model.
Common Screwups
  • ×Sleeping on TSP enrollment in BRS. The 1% automatic plus 4% match if you contribute 5% is the most valuable financial decision of your first enlistment.
  • ×DUI / drug pop — separation under AR 635-200 ch.14 and a re-enlistment code that follows you out the gate.
  • ×ACFT (Army Combat Fitness Test) fails — repeated fails trigger flagging, no promotions, no schools, eventual chapter action.
  • ×Treating OSUT as the hard part. Your first unit's regular PT/CTC train-up is harder and longer than anything at Fort Moore.
  • ×Getting in trouble at the barracks (underage drinking, fighting, AWOL) — Article 15s in your first 12 months bury you on the promotion-point ladder before you ever take a board.

A Day in the Life

  • 0500Wake. Roll out of the rack. Hit the head, shave (yes, even if you do not need to), uniform check, PT clothes on. Make the bed to the platoon SOP — the squad will fail an inspection because of you, not because of itself.
  • 0530PT formation. Stand at parade rest behind your team leader. Accountability check, uniform check, then off to the company PT field.
  • 0600-0700Unit PT. Cardio days the platoon runs together; strength days you may break out into the gym in shifts. Wednesdays are typically heavy ruck or formation run; Friday is FTX-prep day for whatever the platoon is doing that field.
  • 0700-0900Hygiene, change uniforms, breakfast at the DFAC or in the barracks. Some platoons release for hygiene to barracks; others convoy directly back to the company area.
  • 0900First formation. Platoon sergeant reads announcements. TL hands out the day's tasks. You stand still; you listen; you do not check your phone.
  • 0915-1130Work call. Weapons cleaning in the arms room (deep clean PMCS), motor pool (PMCS the vehicles even if you do not drive them), range support (set up targets, run pit detail), or training under the TL (squad-level battle drills, dry-fire, sand-table walkthroughs).
  • 1130-1300Chow. DFAC if you have a meal card; barracks or off-post if you have BAS. Most cherries eat at the DFAC for the first 18 months.
  • 1300-1500Afternoon work call. More of the morning — weapons, motor pool, training, details. Or company-level event: SHARP training, EO training, safety brief, IG brief, ATFP, OPSEC training (mandatory online courses). Sit, listen, sign the roster.
  • 1500-1630Final formation. Squad leader briefs the next day. Sensitive items checked back in. You account for your gear and your weapon — every time, every day.
  • 1630Released. Usually. CQ, staff duty, additional details may extend your day by hours or days.
  • 1700-2000Personal time. Barracks (gym, study, video games, errands), off-post for those with cars, family for the small percentage who are married this young. The cherry mistake here is binge drinking with the squad — three months of weeknight drinking makes for the worst Monday formation read of your young career.
  • 2000-2200Study time (the smart cherry studies the SMCT tasks, the call signs, the platoon SOPs). Phone-call to family. The unit's 22:00 lights-out for barracks soldiers is policy at many BCTs.
  • 2200Lights out. Tomorrow starts at 0500.
  • Field rotationThe clock collapses. Up at 0500 for stand-to; sector for the day; chow when the platoon allows; sleep in 2-4 hour shifts under the poncho. A 5-day FTX feels like 10. A 14-day CTC rotation feels like 30.

Weekly Cadence

The Mon-Fri rhythm for a cherry in a line BCT is dictated by the squad leader's training schedule. Monday is high tempo — PT, weapons maintenance, briefings, paperwork that piled up over the weekend. Tuesday and Wednesday are training days — Sergeant's Time Training (STT) where the TL runs your squad through SMCT tasks and battle drills. These are the days that matter for the EIB conversation. Show up early. Volunteer for the lane. Thursday is often ranges or motor pool day; Friday is the company-level event (PT, hails-and-farewells, awards formation, safety stand-down) and release. The bad cherry coasts through Mon-Wed and tries to make up the work on Thursday; the good cherry hits Mon-Wed hard and is on the short list for the company commander's coin by Friday's formation. The week's second rhythm is administrative. Common task training (CTT), mandatory online courses, SHARP/EO/ATFP cycles, weapons qual cycles, gunnery cycles — these come in waves dictated by the company training schedule. The cherry job is to be present and prepared. The cherry's career-killer is to be the soldier the TL has to chase for an overdue mandatory course at 1700 on a Friday before a long weekend.

Key Skills — How to Drill Each

  1. 01
    Zero and qualify the M4/M16 on TC 3-22.9 standards — distinguished is the bar to chase, expert is the floor.
    Get to the range early. Stack your magazines the night before. Walk the firing line at the briefing and find your lane. Distinguished pistol- and rifle-shooters at the company level look like they're slowing the trigger down — they're not, they're slowing the breath. Dry-fire 200 reps a week in the barracks before you ever touch live ammo. The platoon's range cadre spots a soldier who treats qualification day as the first time he handled the rifle that week.
  2. 02
    Function-check, load, reduce stoppages, and clear the M249/M240/M203/M320 your fire team is built around.
    Memorize the immediate-action drill for each weapon: SPORTS for the M16/M4 family, then the weapon-specific drills from TC 3-22.9 and the weapon's TM. Drill them in the barracks with rubber duck rifles and inert dummies. The TL will run unannounced stoppage drills at random — your reaction time is the read he's making.
  3. 03
    Land nav day and night to STP 21-1-SMCT task 071-329-1019 standard.
    Buy your own commercial map case and a backup compass before you need them issued. Walk a 6-leg course at Smoke Bomb Hill or your installation's land nav site with a battle buddy at least once a month. Day land nav is plotting + pace count + a steady walk. Night land nav is plotting + pace count + believing the compass when your eyes lie to you.
  4. 04
    Battle Drill 1 (squad attack), 2 (react to contact), 3 (break contact), 6 (enter and clear a room) from ATP 3-21.8 chapter 5.
    These are scripts the team rehearses dry, blank, and live. Know your sector (left, right, depth) at every action; know the actions of the team leader and the actions of the rifleman to your left and right. The TL grades you on whether you executed exactly the script briefed — not on whether you improvised. Improvisation at private level is friendly fire.
  5. 05
    Run a CLS-level trauma assessment — MARCH, tourniquet high-and-tight, NCD, hypothermia prevention.
    Get the Combat Lifesaver certification within the first 12 months at the unit. The MARCH algorithm (Massive Hemorrhage, Airway, Respirations, Circulation, Hypothermia) is a 60-second checklist on a stressed patient — drill it until it's automatic. The unit's combat medic will pull you for CLS lanes; volunteer for them.
  6. 06
    Maintain your kit so it survives a 12-mile ruck — tape, dummy-cord, waterproof what matters, throw out what you do not need.
    Lay your fighting load on a poncho in the barracks the night before a movement. Test every snap, every retainer, every drag handle. Tape the noisy buckles. Dummy-cord the NVGs and the optic. Waterproof socks and TQs go in a freezer Ziploc. Everything else goes in the assault pack — and if you didn't use it in the last field, leave it in the barracks for the next one.

Manuals & References — What Chapters Matter

  • STP 21-1-SMCT — Soldier's Manual of Common Tasks, Warrior Skills Level 1.
    This is the validation reference for everything the Army expects from a private. Every Sergeant's Time Training event runs off STP tasks. Print the task cards for the tasks you have not certified on; carry them in your patrol cap.
  • ATP 3-21.8 — Infantry Platoon and Squad (read chapters 1, 4, and 5).
    Chapter 1 is the platoon's job; chapter 4 is the offense; chapter 5 is the defense. Even at private level, knowing the back-brief language your TL uses lets you act before being told. It also tells you what the squad's lanes are testing for.
  • TC 3-22.9 — Rifle and Carbine.
    The weapons manual that the range cadre quotes from. Sections on zeroing, function check, malfunctions, and qualification standards. Read it before your first range, not after.
  • TC 3-21.75 — The Warrior Ethos and Soldier Combat Skills.
    The doctrinal expression of the Soldier's Creed and Warrior Ethos. The platoon sergeant will quote chapter 1 at you. The remainder is the common-task checklist behind the SMCT.
  • FM 7-22 — Holistic Health and Fitness.
    The ACFT plan lives here. Programming for cardio, strength, mobility, sleep, and nutrition. Read it once. Implement the parts your platoon does not already enforce.
  • AR 600-9 — Army Body Composition Program.
    If your tape exceeds the standard for your height, you are flagged for promotion and schools. Know the standard for your age band; know the body-composition assessment procedure (the second-look measurement); know your right to request the body fat tape test.

Standards — How to Hit Each

  • ACFT 500+ to be left alone, 540+ to start getting noticed for schools.
    ACFT 500 is roughly average across the events; 540 puts you above platoon average. Build the score with lift days (deadlift, hex-bar carry, push-up volume), interval runs (the 2-mile is the score-killer), and grip work (the dead-hang on the hex bar is the event most privates underestimate). Squad PT will get you to a 500; personal PT after hours gets you to a 540.
  • Expert Infantryman Badge (EIB) attempt within your first 18 months in the line company.
    EIB is a 5-day train-and-test event your battalion runs annually. The pass rate at first attempt is below 40% in most units — the soldiers who pass on first attempt are the ones who started rehearsing the STP tasks 90 days out, walked the land nav course on their own time, and ran the 12-mile ruck under 3 hours at least twice. Volunteer for the EIB train-up; do not wait to be tasked.
  • Qualify Expert on the M4 every cycle.
    Expert is 36 out of 40 hits on the new TC 3-20.40 / TC 3-22.9 standard. Practice in a 4-stage block: prone supported (most stable, get your zero confirmed), prone unsupported, kneeling, standing. Most missed hits come from the standing position; the 200m and 300m targets are where soldiers shoot below their skill level because they are tired and breathing hard.
  • 12-mile foot march in under 3 hours with 35 lb fighting load — the Air Assault / EIB standard.
    Train at the load you will test at. Do a 6-mile at 30 lb three weeks out, an 8-mile at 35 lb two weeks out, and a 10-mile at 35 lb the week before. Boot break-in matters more than people admit. The standard is a 15-minute mile pace; track each mile on your watch and adjust pace at the 6-mile turn.

Technical Mistakes — Concrete Consequences

  • Treating weapons maintenance as a formation event.
    The TL who finds carbon in your bolt at a random check remembers it for your next counseling. The CO who finds dirty weapons at an unannounced inspection counts the rifles in your squad. The platoon's read of your team starts on the arms-room floor.
  • Skipping the pre-combat inspection (PCI) checklist because 'I had it last time.'
    You did not. The missing NVG cap, the dead PEQ-15 battery, the loose lens on the optic — these surface at the worst time, usually at the start of a lane in front of the platoon sergeant. The PCI is the check that lets you not be the soldier who held up the squad.
  • Buying expensive gucci kit before you own the issued kit.
    The IOTV, plates, helmet, and assault pack are graded; your Crye combat shirt is not. The TL who sees a private wearing a $200 plate carrier over a torn IOTV reads 'priorities not aligned with the squad' and adjusts the school-slot conversation accordingly.
  • Going to sick call only when something is broken.
    Document the sprain in week one or the VA fights you about it in year ten. The cumulative micro-injuries of infantry life — knees, back, shoulders, ankles — become 0% disability ratings if you have no clinic visits in your record. Sick call also resets the platoon sergeant's read of you only if you go too often without cause; balance is the standard.
  • Putting headphones in during downtime in the field.
    You will miss the FRAGO. Your squad will hear about it. The TL will pull you aside and you will spend the next 12 hours overcompensating to rebuild trust you should not have spent in the first place.

Career Decisions at This Rank

  • TSP enrollment under the Blended Retirement System (BRS).
    Everyone enlisted after January 2018 is on BRS by default. The government matches 1% automatically and adds up to 4% more if you contribute 5% of base pay. At E-1 base pay (~$2,100/mo in 2026), that 5% is $105/month — most cherries say they cannot afford it, but they spend more than that on Monster energy drinks and barracks streaming subscriptions. The math: starting TSP at 19 with 5% contribution + 5% match, retiring at 39 after 20 years, gets you a TSP balance roughly 4× what starting at 26 gets you. This is the single most consequential financial decision of your first enlistment. Talk to S-1 in your first week.
  • Volunteer for Airborne / Air Assault / Pathfinder schools.
    These are short, chain-allocated schools that build the career resume. Airborne (3 weeks at Fort Moore) is the standard light-infantry add-on if your gaining unit is airborne-coded; Air Assault (10 days at Fort Campbell) is a common 11B add-on for non-airborne units. Pathfinder was historically a separate course but is now consolidated into Air Assault. The slot is allocated by the chain — the SGT who shows you can be trusted with the slot is the one who pushes you for it. Volunteer early; volunteer for the company workout group that preps for the school; ask the platoon sergeant directly.
  • Stay 11B vs. reclass at the first re-enlistment window.
    The first re-enlistment window typically opens 12-18 months before your contract ends. Reclass options are tied to Army-wide MOS shortages — the available list moves quarterly. If you discover infantry is not for you (the body, the rhythm, the OPTEMPO), the cleanest exit is reclass to a related but lower-impact MOS at first re-enlistment, not chapter discharge. Common 11B reclass paths: 25-series signal, 35-series intel, 68W medic, 18-series SF (via SFAS at first re-enlistment). Talk to the career counselor before signing anything.
  • Marriage and barracks-to-off-post move.
    Getting married as an E-3/E-4 is a financial windfall (BAH bumps from barracks-rate to with-dependents) and a logistical commitment. Off-post housing decisions need PCS analysis (your next move could be in 24 months); spouse employment in military towns is often constrained; child care availability on most posts has a 6-12 month waitlist. The honest test: if the marriage is real and the relationship survived BCT/AIT, the Army's family infrastructure (ACS, Tricare, on-post housing) is functional. If the marriage is for the BAH alone, the relationship will not survive the first PCS.
  • Ranger / SFAS volunteer track (the long-term 11B special-ops play).
    Ranger Assessment and Selection Program (RASP) and Special Forces Assessment and Selection (SFAS) are open to enlisted soldiers from the start. RASP is the entry into the 75th Ranger Regiment (1/75, 2/75, 3/75). SFAS is the gate to the Special Forces Qualification Course (Q Course) — most 11Bs go SFAS later in career, but some Whiskey paths open at first re-enlistment. The decision: are you willing to give up the predictable line-BCT career arc for a higher-OPTEMPO, higher-selection-rigor community? The right answer for some is yes; the right answer for some is no. Talk to NCOs who have been through both pipelines before volunteering.

How the Seat Varies by Unit Type

  • Light Infantry (10th MTN, 25th ID, 101st AAB, 173rd ABCT, 82nd ABN)
    Cherry life in light infantry is foot-mobile, ruck-heavy, and high-OPTEMPO. Your team's training calendar revolves around 12-mile ruck marches, air movements (101st), airborne ops (82nd, 173rd), and the AT/IT rotation. JRTC at Fort Johnson is the home rotation — wet, miserable, OC/T-evaluated. The community values the tab/badge stack (Ranger, Air Assault, Airborne, Pathfinder, EIB) and reads new privates against that stack from day one.
  • Stryker Infantry (2nd Cav in Germany, 2/2 ID JBLM, 1/25 ID Alaska, 3/2 ID JBLM)
    Stryker cherry life is mounted for movement, dismounted for the close fight. The platform is more mobile than a Bradley and more lethal than a Humvee. You'll learn the Stryker variants (the rifle squad rides in the ICV, the weapons squad in the ICVV, etc.) and the mounted-dismounted rhythm. NTC and JMRC are the home rotations. The platoon's tactical SOPs blend light-infantry doctrine with mounted maneuver — neither pure light nor pure mech.
  • Armored / Bradley Infantry (1AD Bliss, 1ID Riley, 3ID Stewart, 4ID Carson, 1CD Cavazos)
    ABCT cherry life is mounted, vehicle-maintenance-heavy, and gunnery-cycle-driven. The Bradley Fighting Vehicle (M2A3/A4) is your home — you'll spend more time on PMCS, gunnery tables (I-VI for crew gunnery, VII-XII for platoon and company), and rolling stock maintenance than on ruck marches. NTC at Fort Irwin is the home rotation — desert force-on-force where the team's gunnery skill is graded by the OC/T.
  • 75th Ranger Regiment (1/75 Hunter, 2/75 Lewis, 3/75 Benning)
    Ranger cherry life is a tier above any line BCT in OPTEMPO and training intensity. Pre-RASP and RASP (Ranger Assessment and Selection Program) are the entry gate. The Regiment runs a faster training cycle and a faster deployment cycle than line BCT. The community values the Ranger Tab + Regiment-specific qualifications (Sniper, Mortars, Master Breacher). Cherry life is structured around becoming a 'Ranger' in the Regiment's sense of the word — the bar is materially higher than 'infantry private' anywhere else.
  • OPFOR / Cavalry Squadron (cavalry scout cherry assigned to a light or armored cav squadron)
    If you went to OSUT as 11B but landed in a cav-organized unit (the 1-1 CAV at Riley, the 2nd CAV in Germany, the 75th Cavalry Regiment slots at Bragg), the rhythm is closer to recon/economy-of-force than direct-action infantry. You will spend more time on reconnaissance fundamentals (FM 3-98), patrol base operations, and route security than line infantry will. The cav community has its own culture and its own school slots (the Recce Leaders Course, Bradley scout-specific gunnery).

What Good Looks Like at This Rank

The good cherry private is invisible the right way: kit squared, weapon clean, sector covered, mouth shut, asking the questions during AAR instead of during the brief. He learns the names of the senior soldiers in his squad by week two. He memorizes the squad's call sign and frequency by week three. He has dry-fired the rifle enough times in the barracks that his trigger discipline at the range looks like a veteran's. He brings extra batteries for the NVG and the radio because he knows somebody will need them. He asks the team leader the question that the TL was about to brief him on, which makes the TL the smartest guy in the conversation — and the TL remembers it. By month nine, the TL is letting him run lanes — short ones, with feedback after each. By month eighteen, he is on the short list for the EIB train-up because the squad leader has watched him show up to optional PT, optional weapons cleaning, and optional weapons-quals prep. By his first re-enlistment window, the squad leader is asking him what school he wants to attend before his second contract starts. The retention NCO has already gotten a heads-up from the SL that this is a soldier worth keeping; the SRB conversation is on the table because the unit has decided he is somebody they want around for the next six years. The bad cherry private is the one who does not understand that being invisible is the goal. He is the soldier who corrects the SGT in front of the squad, who talks during the company-level briefing, who buys gucci kit but does not pre-inspect the issued kit, who shows up late to the range on the day his squad is qualifying. He is not malicious — he is just signaling that he does not yet know what game he is playing. The good cherry is the one who figured out the game in week three and started playing it the right way.

Preview — The Next Rank

E-4 Specialist (or Corporal, if the chain pins you to a team-leader billet) is the next rank, and it is structurally different from E-1 through E-3. E-4 is the first promotion that requires the chain to actively recommend you — 24 months TIS / 6 months TIG, but both clocks can be waived for soldiers who are visibly outperforming the platoon. The chain's recommendation is what moves you from the automatic-promotion track to the recommended track. The job content at E-4 is "senior rifleman." You are the proficiency floor of the squad — the new privates copy how you wear your kit, clear your weapon, and brief a sector sketch. If you are corporal-pinned, you are running a fire team for real: PCC/PCIs, sector assignments, casualty plan, comm plan. If you are still SPC, you are the bench — running the range tower, the radio, the M2 in the turret, the additional duty (arms room, supply, training NCO) that the squad cannot live without. The TL is starting to evaluate you for SGT potential. The differentiator on the SGT board is the school stack (EIB, Air Assault, Airborne, Ranger packet if you are tabbed for it), the BLC slot (required to pin SGT), and the chain's read of whether you can be trusted with a 4-soldier team. Plan the BLC packet 6-12 months before your TIS hits the SGT window. Plan the school packet at the first opportunity. The good cherry private becomes the good SPC by being the soldier the TL points at when the squad has a hard task.
