Military Police

You are the MP officer who learns that law enforcement, detention operations, and combat support are three completely different skill sets — and that your installation, your brigade, and your theater need all three from the same organization simultaneously.

You come out of the Military Police Officer Basic Course (MPOBC) at the Military Police School, Fort Cavazos (renamed from Fort Hood in 2023), and report to your first MP unit — a Military Police Company inside a BCT, a standalone MP Company at a garrison installation, or an Internment/Resettlement (I/R) Battalion. The platoon leader seat in a BCT-organic MP company means you run maneuver support and area security for the brigade — traffic control points (TCPs), detainee handling under FM 3-39 / ATP 3-39.40, site exploitation, and route security. The garrison installation MP platoon means you supervise patrol operations, law enforcement reports, physical security assessments under AR 190-13, and the Desk Operations function that is the visible face of military law enforcement 24 hours a day. You write patrol schedules, manage the serious incident report (SIR) process under AR 190-40, and brief the Provost Marshal on the installation's law enforcement posture weekly. Your platoon sergeant — typically a Staff Sergeant or Sergeant First Class with CID experience or combat rotation time — runs the floor; you run the planning, the resourcing, and the paper trail.

• 01Plan and supervise military police operations across all five MP disciplines — law enforcement, I/R, security and mobility support, police intelligence operations, and area security — per FM 3-39.
• 02Run a traffic control point (TCP) or checkpoint to ATP 3-39.10 standards — site selection, ROE brief, personnel searches, detainee handling, strip map, and SALUTE report flow.
• 03Brief the Law Enforcement and Physical Security Annex (Annex P) to a brigade OPORD — force protection integration, TCP locations, detainee holding area, off-limits areas, serious-incident reporting chain.
• 04Supervise installation patrol operations — patrol scheduling, law enforcement report (LER) quality control, use-of-force documentation, and the 24-hour desk operations brief to the Provost Marshal.
• 05Conduct a physical security assessment of a facility per AR 190-13 — perimeter evaluation, access control points, lighting, barriers, command-and-control — and produce a written findings memo the installation commander can sign.
• 06Sign for and account for sensitive items unique to the MP set: weapons (pistols, less-than-lethal), restraint equipment, Breathalyzer test kits, evidence and property safeguards under AR 195-5.

• —FM 3-39 — Military Police Operations (the branch doctrine bible; read it cover-to-cover at MPOBC and again on arrival at the first unit).
• —ATP 3-39.10 — Police Operations (your patrol-operations and law-enforcement standard).
• —ATP 3-39.30 — Security and Mobility Support (area security, mobility corridor, TCPs — the BCT-organic MP mission set).
• —ATP 3-39.40 — Internment and Resettlement Operations (detainee handling, EPW procedures, I/R facility operations).
• —ATP 3-39.20 — Police Intelligence Operations (criminal intelligence, the PIR/IR development cycle, information-sharing with CID and the BCT S-2).
• —AR 190-13 — The Army Physical Security Program; AR 190-40 — Serious Incident Reporting; ADP 6-22 — Army Leadership and the Profession; DA PAM 600-3 (31A chapter).

• —MPOBC graduate; Law Enforcement Professional (LEP) certification under DA Civilian Police and Guard Program standards where applicable to the billet.
• —OER profile from your first KD that the senior rater can defend — "most qualified" at the top of the rated population, with bullets tied to operational outcomes (TCP throughput, SIR process, physical security findings, detainee operations, soldiers certified).
• —ACFT pass at the officer standard; the MP branch does not get a law-enforcement exemption from the fitness standard.
• —Successful CTC rotation (JRTC, NTC) as the BCT's senior MP officer on the floor — or a real-world contingency deployment with the brigade — where the network of TCPs, the detainee pipeline, and the force-protection annex held.
• —Completion of the MP Officer Advanced Course (MPOAC) slot or equivalency — the gate to captain and company command consideration.

• —Trying to run the patrol section floor as if you are the shift supervisor. Your platoon sergeant runs shift execution; your job is to plan, resource, and brief. The desk sergeant who has to talk around the lieutenant is the desk sergeant who stops trusting the lieutenant inside a week.
• —Missing the SIR timeline. Under AR 190-40, serious incidents report up in defined time windows; a missed SIR notification to the Provost Marshal and the garrison commander is a chain-of-command failure with your signature on it.
• —Confusing law enforcement evidence procedures with tactical site exploitation. LERs, chain-of-custody documentation, and evidence handling under AR 195-5 operate on different standards from tactical DOMEX/CELLEX; conflating them creates inadmissibility problems and AR 15-6 risk.
• —Letting use-of-force documentation lag. Every incident requiring force above verbal direction needs a documented DA Form 3975 and a use-of-force memo within 24 hours. A stack of undocumented incidents is a commander's inquiry waiting to happen.
• —Ignoring the METL gap between BCT-organic MP operations and I/R operations. Officers who arrive at a garrison MP company having only trained on TCPs and route security need to rapidly develop I/R doctrine familiarity — ATP 3-39.40 is not optional when an internment mission surfaces.

The good 31A LT is the one the BCT S-3 calls before the CTC rotation because the force-protection annex is always clean and the TCP network is always resourced. On the installation side, the good LT is the one the Provost Marshal puts at the desk operations brief because the SIR process is current, the serious-incident documentation is litigation-proof, and the Soldiers know the standard because he counseled them honestly, not because he threatened them loudly.

You are the MP company commander or the installation Provost Marshal deputy — the officer who runs a 100-200 soldier law enforcement and combat-support formation, defends the installation's physical security and law enforcement posture, and translates the maneuver commander's force-protection intent into a working plan the NCOs can actually execute.

You return to Fort Cavazos for the Military Police Captain's Career Course (MPCCC) — roughly 5-6 months at the MP School, covering company-grade MP operations, I/R operations at operational scale, police intelligence operations, installation law enforcement management, and the staff and leadership skills that maneuver branches expect from their peer captains at brigade and division. From there, you slate to a KD: MP Company Command (a BCT-organic or theater-level company — 100-200 soldiers, multiple platoons running law enforcement, TCPs, area security, or I/R), Installation Provost Marshal Staff (PM office at a major installation — running the civilian police and guard program, physical security, traffic law enforcement, and the SIR reporting chain to garrison command and HQDA G-2/Provost Marshal General), or a staff billet at BCT S-3, division G-3 (force protection cell), or HQDA Provost Marshal General (HQDA PMG) at Fort Belvoir. After company command, the competitive major fights for an MP Battalion S-3/XO seat — the field-grade KD that gates battalion command consideration. The theater provost marshal (TPM) and PMG staff are the post-KD destinations that build the field-grade competitive record. Special operations support (theater internment, detainee operations in austere environments) and joint assignments (JTFHQ force protection, SOCOM detainee handling cells) are the billets that differentiate the competitive major's record from the solid-but-conventional one.

• 01Command an MP company — train, certify, deploy, and sustain a 100-200 soldier formation with law enforcement, detainee operations, area security, and police intelligence equipment — through a CTC rotation or real-world deployment without losing the force-protection annex or the detainee pipeline.
• 02Run an installation law enforcement and physical security program as PM or PM deputy — the patrol schedule, the SIR process, the physical security inspection program, the anti-terrorism program, and the civilian police and guard force — at the level the garrison commander calls "PM shop is solid" at the installation staff meeting.
• 03Defend the I/R operations plan and the detainee operations annex in a BCT OPORD brief — EPW/CI handling, internment facility siting, medical screening, and transfer procedures under ATP 3-39.40 — to the standard the theater JALLC or ICRC inspection accepts.
• 04Mentor a company of officers and NCOs through KD time, schools, and OER/NCOER cycles — your OERs on your lieutenants are the documents the O-3 promotion board reads; your NCOER on your first sergeant is the document the E-8 board reads.
• 05Translate force protection and law enforcement risk to a maneuver commander or a one-star in language they will repeat correctly to the next echelon — and translate the commander's force-protection intent back into a patrol plan the desk sergeant and the sector NCO can actually execute.
• 06Navigate the functional area (FA) and branch transfer decision honestly — FA30 Information Operations, FA49 Operations Research/Systems Analysis, 35A Military Intelligence, or the Interagency path (DoJ, FBI, DHS, CBP, USMS) — based on talent, market, and the post-command billets the trajectory actually supports.

• —FM 3-39 — Military Police Operations; ATP 3-39.10 — Police Operations; ATP 3-39.30 — Security and Mobility Support; ATP 3-39.40 — Internment and Resettlement Operations.
• —ATP 3-39.20 — Police Intelligence Operations; ATP 3-39.32 — Civil Disturbance Operations.
• —AR 190-13 — Army Physical Security Program; AR 190-40 — Serious Incident Reporting; AR 190-5 — Motor Vehicle Traffic Supervision; AR 195-2 — Criminal Investigation Activities.
• —AR 600-20 — Army Command Policy; AR 623-3 — Evaluation Reporting; AR 350-1 — Army Training; AR 600-8-29 — Officer Promotions.
• —DA PAM 600-3 — Officer Professional Development (31A/MP chapter); ADP 6-0 — Mission Command; ADP 6-22 — Army Leadership and the Profession.
• —JP 3-63 — Detainee Operations (joint-level doctrine for internment at theater scale); DoDD 2310.01E — DoD Detainee Program (the policy authority behind all I/R operations at operational and strategic level).

• —MPCCC graduate; ILE/CGSC slate at Fort Leavenworth (resident or non-resident) before the major's board.
• —Successful KD OER — MP Company Command or PM deputy — with senior rater profile and bullets tied to measurable outcomes (CTC rotation, SIR process compliance, physical security findings closed, I/R capacity maintained, soldiers certified and accredited).
• —Law Enforcement Professional (LEP) certification current; CBRN / force protection officer additional qualification where coded to the billet.
• —JDAL (Joint Duty Assignment List) credit on the path to O-4 / O-5 — theater provost marshal, joint task force MP officer, JTFHQ force protection — more valuable to the MP field grade record than a second conventional garrison tour.
• —For the centralized HRC command and major's board: pull the current Officer Personnel Management Directorate (OPMD) board release for MP branch — promotion-zone math under DOPMA and AR 600-8-29 moves, and the published board demographics are the only honest source.

• —Treating company command as a law enforcement problem instead of a soldier problem. The KD is a formation-leadership and property-accountability problem — the patrol plan and the SIR process are what you brief, but the soldier climate and the property book are what the brigade and the garrison CSM are watching.
• —Hiding a pattern-of-conduct finding or a SIR-noncompliance trend from the garrison commander to "get it fixed before the report." It surfaces. The command investigation is at the garrison level and the major's board reads the OER.
• —Letting the detainee operations annex become a template-fill exercise. The ICRC or JALLC inspection reads the annex for substance; a form-filled annex with no living SOP behind it is the mistake that surfaces on day two of the detention operation, not day one.
• —Confusing tactical MP expertise with the provost marshal staff function. The post-KD slate (PM office, HQDA PMG, theater provost marshal) requires honest self-assessment about which lane fits the trajectory; captains who fake PM-staff depth at the field-grade table are visible inside a meeting.
• —Skipping the interagency and functional-area conversation because "I am an MP officer." DA PAM 600-3 names the FA and interagency paths explicitly; the captains who think through the next assignment honestly are the ones the OPMD branch manager calls first when the interesting billets open.

The good 31A captain commanded an MP company that did not lose the force-protection annex at NTC/JRTC, certified every platoon leader through the full five-discipline MP mission set, and turned over a formation with a property book and a SIR history the next CO did not have to defend against. As a major, he is on a battalion S-3/XO slate at an MP Brigade or Theater Sustainment Command; his ILE is complete; his joint tour (theater PM, JTFHQ) is either finished or scheduled; and the centralized command board reads his OER profile and selects him for MP battalion command without a long debate. Pull the current HRC board release for the actual selection demographics — the rest of the math is already on the slide.
