Light-Armored Reconnaissance (LAR) Officer

You are the LAR platoon commander. You went through TBS and IOC same as every other 0302, then you volunteered, were selected, and drove to 29 Palms with a secondary MOS designator that tells the battalion you know what a LAV-25 actually does. You are not an infantryman on a vehicle — you are a reconnaissance and screening officer who happens to fight through when the mission demands it. The platoon sergeant has been inside LAVs longer than you have been commissioned. Learn the ground first.

You arrive at an LAR battalion — 1st LAR at Pendleton, 2d LAR at Lejeune, or 3d LAR in 29 Palms — after completing the LAR Officer Course at MCAGCC Twentynine Palms following TBS and IOC. Your billet is LAR platoon commander: a platoon of LAV-25A2s and their variants, the crews who operate them, and the scouts who dismount when the terrain demands it. Your day-to-day is the same as any rifle lieutenant — OPORD construction, troop-leading procedures, FitRep counseling, range packets, the company training meeting — with the added weight of combined arms integration, vehicle maintenance readiness, and the LAR battalion's primary screening and reconnaissance mission. You plan and brief routes and axes of advance, screen-line assignments, and limited objective attacks in which the 25mm chain gun and the ATGM variant are the decisive systems, not the dismount. Garrison life is punctuated by vehicle maintenance and crew gunnery qualification cycles; the maintenance platoon is your shadow and a sick LAV is your problem to fix before the next battalion field exercise. The intelligence collection mission — MEWSS, LRSR, reporting contact to higher — means your S2 is in your planning cycle in ways a rifle lieutenant rarely experiences.

• 01Brief a clean OPORD for a screen, guard, or covering-force mission inside the battalion scheme of maneuver per MCDP 1-3 and MCRP 3-12 — graphics at the right scale for vehicle movement, contact reporting plan built in, fire support plan coordinated before the brief.
• 02Execute troop-leading procedures from mission receipt through rehearsal per MCDP 1-3 and MCRP 3-10A.4 — the rehearsal step for a LAR platoon includes crew confirmations on sector assignments and direct fire control measures, not just dismount actions.
• 03Understand and brief the LAV-25A2 family capabilities and limitations — 25mm M242 Bushmaster effective range, LAV-AT TOW employment constraints, LAV-MEWSS SIGINT reach, LAV-M 81mm mortar planning factors — to the standard where the company commander does not have to correct your employment during the back-brief.
• 04Coordinate joint fire support as the platoon commander during a combined arms problem per MCRP 3-01A — call for fire format, CAS 9-line, JTAR, and the coordination measures that separate your direct-fire sector from the supporting arms impact zone.
• 05Write FitReps on the platoon sergeant and section leaders per MCO 1610.7 — initial counseling within the required window, event-driven entries tied to observed performance, the relative-value ranking conversation with the company commander before the cycle closes.
• 06Read terrain for vehicle movement at speed — trafficability analysis, blade-width corridors, fording depth against LAV water-crossing doctrine — because a LAV platoon that gets channelized in terrain the lieutenant did not analyze is a platoon that has already lost.

• —MCDP 1 — Warfighting (the doctrinal foundation you brief from; LAR's maneuver-warfare identity is written explicitly into this document).
• —MCDP 1-3 — Tactics (the conceptual spine of every screen, zone-recon, and limited objective attack you plan at platoon level).
• —MCRP 3-12 — Light Armored Reconnaissance (the LAR-specific tactics, techniques, and procedures manual; the company commander and the battalion S-3 quote from it).
• —MCRP 3-10A.4 — Marine Rifle Platoon (the TLP and order-writing standard that still applies; LAR platoon missions use the same format with vehicle-specific annexes).
• —MCRP 3-01A — Close Air Support (the CAS 9-line, JTAR, and coordination measure procedures you will use during any combined arms exercise at ITX or field problem).
• —MCO 1610.7 — Performance Evaluation System (the FitRep procedural requirements; own this before your first rater-ratee touchpoint with the platoon sergeant).

• —TBS graduate (The Basic School, Quantico) and IOC graduate (Infantry Officer Course, Quantico) — 0303 is a secondary designator added to 0302; LAR selection occurs after IOC and prior to fleet assignment.
• —LAR Officer Course graduate (MCAGCC Twentynine Palms) — the MOS-qualifying school for 0303; covers LAV-25 family employment, LAR tactics, and combined arms integration at the platoon level.
• —Vehicle crew gunnery qualification on the LAV-25A2 — the crew gunnery table standard defined in the LAR T&R Manual (NAVMC 3500-series); a platoon commander who has not qualified with his crew is not yet the platoon commander.
• —PFT and CFT at the 1st-Class level per MCO 6100.13 — your platoon holds the same standard; you do not get to fall out of anything your scouts and crew chiefs complete.
• —O-1 to O-2 is timeline-driven; O-2 to O-3 (Capt) is a board with historically high-but-not-guaranteed selection — pull current MMPB promotion board releases rather than relying on rumored percentages.

• —Treating the LAR platoon as an infantry platoon that happens to have vehicles. Scouts dismount; vehicles do not park. A platoon commander who defaults to dismount-only tactics and fails to employ the 25mm or the ATGM variant during a combined arms exercise has wasted the primary advantage of the platform — and the battalion S-3 writes the AAR.
• —Cutting the reconnaissance handoff. LAR's primary mission is to find, fix, and report — not to hold terrain. A lieutenant who commits the platoon to a fight the mission did not authorize, without reporting contact and passing the information to higher, has violated the battalion's ability to decide. The company commander finds out in the debrief.
• —Missing the vehicle maintenance window. A LAV with a deferred maintenance squawk that grounds it during a battalion field exercise is a visible failure: the company commander counts vehicles on line at start of exercise. A lieutenant who does not own the maintenance cycle will not have a full platoon when it matters.
• —Posting OPSEC-relevant content — vehicle positions, unit patches, field exercise locations, equipment configurations — on personal devices or social media. The S2 runs sweeps and the battalion commander sees the findings.
• —Skipping the terrain analysis step in route planning. LAVs are not tanks but they are not RZRs either; a platoon committed to a route the lieutenant did not evaluate for trafficability, fording points, or restrictive terrain can get a vehicle mission-killed before the first shot is fired.

The good LAR platoon commander arrives at the company back-brief with a scheme of maneuver the company commander does not have to rewrite — sectors assigned, fire control measures on the overlay, supporting arms coordinated, and the contact reporting plan already rehearsed with the section leaders. The platoon sergeant trusts him to listen during the terrain analysis and push back when the plan does not survive the map. By the end of the first gunnery cycle his crew qualification records are clean, the maintenance log has no deferred squawks, and the battalion S-3 calls him by name when allocating screen assets for the next battalion field exercise — not because he is the most experienced lieutenant in the company, but because his platoon shows up ready.

You are the LAR company commander, or the field-grade officer whose command tour is the ledger every board from here to colonel audits without apology. Company command in an LAR battalion is a combined arms problem: a combined anti-armor company, a headquarters element, and a collection mission that runs through the battalion S-2. The FitRep from that tour does not depreciate.

Your captain arc in an LAR battalion moves through post-LT staff utilization — battalion S-3 air, BN S-1, regimental staff — followed by company XO (the proving ground) and then company command: a LAR company of four to six LAV platoons, a headquarters element, and the combined-arms planning load that comes with it. As company commander you own the training plan, the property book for the LAV fleet and its sensitive ancillary systems, the FitRep cycle on six to eight officers and senior SNCOs, UCMJ authority at the company grade, and the boundary between the battalion commander's scheme of maneuver and what the company can actually execute. The pre-deployment workup — ITX at Twentynine Palms, combined arms exercises at MCAGCC, or a JRTC rotation — is the window the regimental commander and the MEF's O/C/T evaluators use to calibrate the company commander. You will run screens at battalion and regimental scale, coordinate direct and indirect fire in the same planning cycle, integrate MEWSS ISR products into the battalion's common operating picture, and hand off reconnaissance lanes to the follow-on ground combat element. Post-command you move into a senior captain billet — BN S-3, BN XO, regimental staff plans — or the Expeditionary Warfare School pipeline. As a major you are on staff: BN S-3, BN XO, or a joint billet where the combined arms background reads as a competitive differentiator. The Maj board is the first genuinely competitive selection; the LtCol board is the career gate. MMPB manages assignment; FitRep relative-value ranking against peers is the single largest input to both boards.

• 01Plan and brief a company OPORD for a screening, zone-reconnaissance, or guard mission inside the battalion scheme of maneuver — supporting arms integrated with the FSC, contact reporting plan down to section leader, sustainment plan defensible, command-and-signal annex the platoon commanders can execute on degraded comms.
• 02Run the company through ITX at Twentynine Palms or a pre-deployment combined arms exercise as the commanding officer — the O/C/T evaluator writing the after-action review is a major or senior captain whose assessment reaches the regimental commander before you brief the AAR yourself.
• 03Manage the company property book for the LAV fleet and sensitive systems — a change-of-command inventory with unreconciled serial numbers for a main armament or a MEWSS component triggers a financial liability investigation and the battalion commander signs the outgoing documents.
• 04Execute company-level UCMJ — counseling, NJP authority at the company grade, separation action initiation, SJA coordination — documented, procedurally defensible, and closed before the issue becomes a battalion commander problem.
• 05Write FitReps on six to eight rated officers and senior SNCOs per MCO 1610.7 — the relative-value ranking you assign determines which of your lieutenants gets the next KD slate and the company commander slot conversation inside three years.
• 06Translate the battalion commander's intelligence collection requirements into actionable platoon-level reconnaissance tasks — as LAR company commander, the battalion S-2's CCIR lives in your platoon commanders' sector assignments, not just in their awareness.

• —MCDP 1 — Warfighting; MCDP 1-3 — Tactics (the doctrinal framework you teach lieutenants from; at company command you are executing, not learning).
• —MCRP 3-12 — Light Armored Reconnaissance (the company and battalion-level TTP manual the battalion S-3 and the regimental staff quote from; own it and know which sections the O/C/T evaluator reads first).
• —MCWP 3-01 — Offensive and Defensive Tactics for the MAGTF (the combined arms context your company fits inside at ITX and during any MEF-level exercise).
• —MCO 1610.7 — Performance Evaluation System (the FitRep mechanics for six to eight rated officers; the relative-value ranking is the lever; the PRO/CON recommendation from the battalion commander is what the Maj board actually reads).
• —MCO 1400.32 — Marine Corps Promotion Manual (Maj board mechanics, IPZ/BZ/AZ math, FitRep RV weighting — understand the board architecture before your command-tour OER cycle).
• —JP 3-09 — Joint Fire Support; JP 3-0 — Joint Operations (the joint context your BN S-3 and regimental staff billets require; LAR's reconnaissance and screening mission at the MEF level is a joint coordination problem).
• —MCO 1540.8 series — Officer PME; EWS and Command and Staff College catalog (the PME gates the LtCol board reads as proof the institution believes in the officer's future).

• —Company command tour — 18-24 months, slated by the battalion commander and confirmed through MMPB. The single FitRep the Maj and LtCol boards weight more heavily than every other report in the file. One weak relative-value ranking in the command tour compresses the board read in ways a strong narrative cannot recover.
• —ITX / combined arms exercise / pre-deployment workup as company commander — the most-observed performance window of the captain career. The MEF commanding general's staff sees the final exercise AAR; the regimental commander and the battalion commander both sign the outgoing FitRep that covers this window.
• —FitRep relative-value ranking above the peer group average in the battalion during command — the PRO/CON recommendation and the RV stack are the inputs the Maj board actually reads; everything else in the package is context.
• —Expeditionary Warfare School (EWS) or Command and Staff College resident selection — the PME credential the LtCol board reads as institutional endorsement. Pull the current MMPB guidance on selection rates rather than relying on cycle-to-cycle rumor.
• —Maj board at the IPZ window — the first genuinely competitive selection in the Marine officer career. Pull the current MMPB promotion board release for the actual FY selection rate.
• —B-billet or career-broadening tour between KD tours (recruiting duty, NROTC instructor, TBS or IOC instructor cadre, joint billet) — visible to the LtCol board as breadth and named in the FitRep by the senior rater.

• —Treating ITX as a box to check rather than the evaluation window it is. The O/C/T team at MCAGCC is watching the company commander's decision-making under friction, not the platoon commanders' individual performance — a company that executes technically correct drills with a commander who cannot adapt the scheme of maneuver to changed contact is a company that gets a mediocre AAR read, and the regimental commander hears it.
• —Losing the command-tour FitRep on a recoverable problem. A command investigation, a lost sensitive item from the LAV fleet, a range incident requiring battalion-level inquiry — these do not end the career immediately, but they materially compress the Maj and LtCol board reads in a community small enough that the reporting chain is the same four officers for six years.
• —Mishandling UCMJ at the company level. An NJP a Marine successfully appeals, a separation packet the battalion commander has to fix, a counseling record that does not support the action taken — the BN CDR remembers which captains needed legal supervision and the FitRep comment is permanent.
• —Ignoring the FitRep relative-value conversation with the battalion commander. The PRO/CON recommendation and the RV stack are what the Maj board actually reads; captains who do not understand the relative-value ranking mechanics end up in the bottom tier of a peer group they outperformed in the field.
• —Arriving at the BN S-3 or BN XO billet post-command without treating it as seriously as the command tour. The regimental commander is reading the staff product; the post-command billet is the FitRep that determines EWS selection and the LtCol board signal — coast here and you turn one strong command tour into a mixed file.

The good LAR company commander runs a company the battalion commander sends to the most complex combined arms problem in the workup without worrying about the AAR. The property book reconciles. The Article 134 packets are SJA-defensible. The four platoon commanders inside his company are on FitReps the senior rater can profile honestly — and at least one of them is already named in the company command slate conversation two years out. The good senior captain post-command is the BN S-3 whose staff product the battalion commander briefs with, not around — the OPORD annex gets read once and signed. The good just-pinned major is the officer whose name the regimental commander already gave the MMPB assignment monitor before the EWS selection board sat, because the command tour confirmed what the file was already suggesting.
