Armor

You are the tank platoon leader or cavalry troop PLT leader. The platoon sergeant has 15 years in the seat you just inherited. Your job is to master the gunnery, read the ground, and plan the fight — not to compete with the SFC who already knows where every bolt on the M1A2 lives.

You commission and report to Fort Moore for ABOLC (Armor Basic Officer Leader Course) — roughly 18 weeks under the Armor School and the Maneuver Center of Excellence — covering M1A2 Abrams tank operations, crew gunnery, Bradley and Stryker familiarization (if slated to a cav squadron), reconnaissance and security doctrine, and the tactical decision games that separate armor officers from observers. Your first KD is platoon leader: four M1A2 Abrams SEP v3 tanks and 14 soldiers in an Armored BCT (ABCT) at Fort Bliss, Fort Cavazos, Fort Stewart, Fort Hood / Cavazos, or Germany (2nd Cav Regt at Vilseck / 12th ABCT); or, if branched into Cavalry, a Stryker Cavalry Scout platoon in an SBCT cav squadron (M1127 Recon Vehicle / M1131 Fire Support Vehicle), or a HMMWV-mounted scout platoon in an IBCT cav squadron. You own the platoon's gunnery program, the maintenance posture on four 70-ton tracked vehicles, the crew qualification cycle, the OPORD build, and the troop-leading procedures the SFC is watching you execute. The unglamorous parts: property-book hand-receipts for M1A2 systems worth tens of millions of dollars, PMCS officer-in-charge during motor pool Mondays, DTS for school packets, and NTC rotation prep packets that hit the S-3 section months before you roll through the breach lane. The meaningful parts: leading a tank platoon through a force-on-force Stryker defense at JRTC or an M1A2 live-fire table at Grafenwoehr — and writing the OPORD the company commander does not have to fix.

• 01Brief a platoon OPORD inside the tank company scheme of maneuver — task-and-purpose, scheme of fire, phase-line triggers, fire-control measures (trigger lines, engagement areas, final protective fire), and ATP 3-20.15-compliant gunnery plan — to a standard the CO does not rewrite.
• 02Run crew-gunnery tables as the tank platoon leader — Table VI through Table XII on the M1A2 SEP v3 per TC 3-20.31 — understanding the fire-control system, SABOT/HEAT/MPAT/STAFF round employment, and the engagement priority you pass to four tank commanders.
• 03Apply troop-leading procedures (TLP) end-to-end per ADP 5-0 — issue the WARNO, develop the COA, back-brief, issue the five-paragraph OPORD, conduct rehearsals on a terrain model the gunners understand, supervise execution — and hit the rehearsal step every time.
• 04Read terrain through an armor and cavalry lens — defensible ground, dead space, avenue of approach width for a tank, engagement area geometry — and translate that into a fire plan the supporting field artillery officer can integrate.
• 05Own the platoon's maintenance accountability: PMCS schedule, deadline tracking, DA Form 2404/5988-E deficiency documentation, and the conversation with the company XO when a tank tracks slip on a road march two weeks before gunnery.
• 06Develop the platoon sergeant / section sergeants through initial and quarterly DA 4856 counseling per AR 623-3, OER support form conversation with the rater, and a genuine bottom-up read on soldier welfare that the chain can act from.

• —FM 3-96 — Brigade Combat Team (the BCT doctrinal spine — armor officers plan against this for the first decade of their career).
• —ATP 3-20.15 — Tank Platoon (your primary platoon-level reference — own Chapter 3 offense, Chapter 4 defense, and the fire control measures annex before your first NTC rotation).
• —ATP 3-20.97 — Cavalry Troop; ATP 3-20.98 — Reconnaissance Platoon (mandatory for 19A cav-slated officers).
• —TC 3-20.31 — Crew Gunnery (the M1A2 gunnery tables reference — know the Table VI-XII sequence before your gunnery OIC conversation with the BC).
• —ADP 3-90 — Offense and Defense; ADP 3-0 — Operations (the conceptual framework your OPORDs frame from).
• —AR 623-3 + DA PAM 623-3 — Evaluation Reporting System; AR 600-20 — Army Command Policy.

• —ABOLC graduate — ~18 weeks at Fort Moore under the Armor School. Class standing travels to your branch manager and the gaining BCT CDR reads the small-group-leader narrative.
• —Crew-qualified on the M1A2 Abrams SEP v3 through Table XII as platoon leader — if you pin two 1LT stars without a Table XII score the BC already knows and the OER reads it implicitly.
• —Ranger School slot — not technically required for 19A in a line ABCT, but the community math is the same as 11A: the BN CDR's read for the first OER assumes a Ranger effort; the Tab is the visible screen signal at the O-3 and O-4 boards.
• —ACFT 540+ floor, 580+ if pushing for Ranger or specialty schools — the platoon tracks the score the PL posts because it sets the standard they are held to.
• —O-1 to O-2 is time-based at 18 months commissioned under AR 600-8-29; O-2 to O-3 boards with very high historical select rates — pull the current HRC Armor branch promotion release rather than relying on word-of-mouth percentages.

• —Out-leading the platoon sergeant on crew drills and vehicle knowledge. The SFC runs the crew room; the LT runs the platoon. LTs who try to be the best gunner in the platoon lose the SFC's trust and the company commander's confidence simultaneously — usually inside 60 days.
• —Cutting the rehearsal step. The tank crew that did not rehearse the EA geometry cold on a terrain model before the NTC lane fires into the wrong sector at H-Hour. That OER gets rewritten.
• —Missing property-book accountability on M1A2 subsystems — CITV, primary sight, thermal imaging system components, crypto. A serialized component unaccounted for is a 15-6 investigation, and the BCT CDR sees the outbrief.
• —Sloppy gunnery prep. A tank platoon that arrives at the firing point with a thermal sight in maintenance status, a dead battery on the bore-sight device, or an inaccurate POSNAV solution fails the table and the platoon leader carries the failure to the OER bullet.
• —Skipping or thin counseling on the platoon sergeant and SSG tank commanders. No paper trail when a soldier issue escalates = no chain-of-command defense for the LT.

The good Armor LT is the platoon leader the company commander sends to brief the BN CDR without editing the brief first. His gunnery prep packet has the BC's corrections already worked in before it hits the S-3. His SFC trusts him enough to tell him honestly when the platoon's engagement-area geometry is wrong — and the LT adjusts without making it a power contest. By the second OER cycle: Ranger Tab if the slot existed, Table XII complete, property book clean, and the senior rater's block reads "select for MCCC; command-slatable captain" — the only two things that matter at this rank.

You are the tank company commander or cavalry troop commander, or the just-pinned major writing the squadron OPORD the troop commanders execute. Company/troop command is the load-bearing OER for every promotion board through O-6. The Army decides what kind of armor officer you actually are by what happened in your company area and at NTC.

The pipeline moves in a known order: post-LT staff utilization (BN S-1, S-4, AS3 operations assistant, or BCT staff billet) → MCCC (Maneuver Captains Career Course at Fort Moore, ~22 weeks under the 199th Infantry Brigade and the MCoE, shared with 11A and 19A officers) → company or troop command (tank company in an ABCT, cavalry troop in an SBCT or IBCT cav squadron — 18-24 months under AR 600-20) → senior captain billet (BN S-3 operations officer or BN XO) → major pin with ILE / CGSC slating at Fort Leavenworth. As a tank company commander you own 14 M1A2 Abrams, three platoons, 60-80 soldiers, the company gunnery program, the property book, UCMJ authority, and the bottom-line OER that defines your file for the O-4 board. As a cavalry troop commander you own a mixed formation — scout platoons, a mortar section, an FIST team — and the squadron CDR is grading your screen, guard, cover, and zone-recon execution. Post-command as a senior captain or junior major, you live on staff — BN S-3 or BN XO — building the OPORD the company commanders execute and defending the squadron's training plan at the BCT BUB. As a MAJ at ILE / CGSC and beyond, the captain years are now a fixed input: the OER block and the command-tour narrative follow the file to every subsequent board.

• 01Write and brief a tank company or cavalry troop OPORD inside the battalion or squadron scheme of maneuver — fires plan integrated with the FSCOORD, breach or passage-of-lines graphics defensible, EA geometry rehearsed by the platoon leaders before the BN CDR back-brief.
• 02Run a CTC rotation as the commander — NTC at Fort Irwin is the home rotation for ABCT units; JMRC Hohenfels for Germany-based 2nd Cav Regt; JRTC Fort Johnson for Stryker cav. The AAR follows your file; the O/C/T narrative is written by O-4s and O-5s who know what good looks like.
• 03Manage company-level UCMJ — counseling, summarized and company-grade Article 15 authority, separation actions via BN S-1 and TDS, AR 27-10 compliant at every step.
• 04Sign for and survive a change-of-command inventory on a tank company property book — M1A2 SEP v3 systems worth hundreds of millions of dollars aggregate, COMSEC fill devices, associated subsystems. The AR 15-6 that results from a missing sight system is signed by the BCT CDR.
• 05Run the squadron gunnery program as the S-3 (pre- or post-command): TC 3-20.31 table sequence, range allocation with the installation range control, MILES / live-fire safety-T validation, crew certification tracking for 14-30 crews across the battalion or squadron.
• 06Translate commander's intent two echelons down cleanly. As CO, the BCT CDR's intent has to live in your platoon leaders' OPORDs without you rewriting them; as MAJ on staff, the division CG's intent lives in the brigade OPORD without a paragraph gap the platoon leaders exploit during execution.

• —FM 3-96 — Brigade Combat Team (the doctrinal spine — own the armor and cavalry tasks, the SBCT scheme, and the reconnaissance-and-security framework for cav operations).
• —ATP 3-20.96 — Cavalry Squadron; ATP 3-20.97 — Cavalry Troop (mandatory for cav-command officers; the squadron CDR quotes both).
• —ATP 3-20.15 — Tank Platoon; ATP 3-20.5 / TC 3-20.31 — M1A2 gunnery references (you are running the program now, not just shooting in it).
• —ADP 3-0 — Operations; ADP 5-0 — The Operations Process; ADP 6-0 — Mission Command (the field-grade conceptual spine).
• —AR 600-8-29 — Officer Promotions, Active Duty; DA PAM 600-3 — Officer Professional Development (IPZ / BZ math, KD timing windows, FA designation conversation).
• —AR 623-3 + DA PAM 623-3 — Evaluation Reporting System; AR 735-5 — Property Accountability; AR 27-10 — Military Justice.

• —MCCC graduate — ~22 weeks at Fort Moore. Small-group leader reads travel to branch manager; class standing in the armor / cavalry cohort matters inside the ABCT community.
• —Company or troop command tour — 18-24 months, slated by BN CDR / BCT CDR / HRC branch manager. The single OER that the O-4 board reads with more weight than every other OER in the file combined.
• —CTC rotation as company commander — the most-watched and most-written-about performance window of your career. The NTC AAR follows your file.
• —Functional Area designation at ~7-8 years commissioned per DA PAM 600-3 — FA40 Space, FA48 FAO, FA50 Force Management, FA51 Acquisition (ground combat system PM offices recruit armor officers), FA52 Nuclear/CWMD, FA59 Strategist. The FA designation shapes O-5/O-6 utilization in ways the branching officer underestimates at MCCC.
• —O-4 board at IPZ window (~10 years commissioned per current AR 600-8-29). Selection rates vary by year; pull the current HRC board release rather than assuming any number.
• —ILE / CGSC at Fort Leavenworth — resident or non-resident per HRC slating. Resident CGSC is the field-grade staff credential and a visible competitive input at the O-5 and O-6 boards.

• —Phoning MCCC. The small-group leaders are former tank company and troop commanders evaluating you against your peer cohort, and the read travels to your branch manager before you arrive at the gaining BCT for command-slate consideration.
• —Coasting on the staff tour. The BCT CDR's read of your S-3 or S-4 staff product is the leading indicator for whether you make the command slate — BCT staffs are small, and the BDE CDR and BCT CSM know which captains produce and which ones manage up.
• —Losing the command OER. AR 15-6 investigations, GO inquiries, IG complaints upheld, negligent discharge on a range under your command — these compress the O-4 board read in a way the rater narrative cannot fully repair. One bad event is survivable; the pattern matters.
• —Missing a change-of-command inventory item on M1A2 subsystems. A CITV or thermal sight system missing from the property book on transfer day triggers a FLIPL; the BCT CDR signs it and both officers carry the notation.
• —Skipping the Functional Area designation conversation. The FA selected at 7-8 years shapes the post-command O-5 utilization in ways that are very difficult to reverse — officers who default into the broadest-access FA without intent find themselves competing for O-6 slating in a lane they did not plan for.

The good Armor CPT commands a tank company or cavalry troop that the BCT CDR is willing to send to the worst NTC rotation because they will not embarrass anyone on the AAR slide. His property book closes cleanly. His platoon leaders leave his command window writing OERs the senior rater can honestly profile above center-of-mass. His Article 15 packets are TDS-defensible and his company's gunnery program produced more Table XII firers than any other company in the squadron. The good post-command senior captain is the BN S-3 or XO the BN CDR briefs with instead of at — the colonel reads the staff product once and signs it. The good just-pinned Armor MAJ is the officer the BCT CDR mentioned on the command-slate slide before ILE, and the one whose CGSC selection arrived as confirmation of what the brigade already knew about him.
