  * Ensure training and certifications completion for all assigned rear detachment sergeant first class
  through sergeant major, chief warrant officer/CW2, and captain through colonel, for casualty
  notification and assistance officers.
  * Be familiar with fatal incident requirements and briefing responsibilities per AR 638-34, Army
  Fatal Incident Family Brief Program.
  3-41. The S-1 should provide the S-3 with the unit's incoming gains roster to designate times and resources
  for theater specific individual readiness training. This coordination and execution before departure will
  directly affect a unit's deployed strength.
  3-42. Battalion S-1s coordinate with the unit commanders to ensure they closely monitor medical readiness
  programs routinely. The non-deployable categories increasing the most before deployment are temporary and
  permanent profiles and referrals to the MAR2/Medical Evaluation Board/Physical Evaluation Board.
  Battalion S-1s should reinforce to unit commanders the need for them to monitor their Soldiers continuously
  to ensure they complete their regular birth-month medical checks. These checks are a precautionary step in
  identifying medical conditions and correcting them before deploying. Battalion S-1s should encourage
  commanders to make decisions on Soldiers who are borderline for deployment as early as possible. If
  deployability decisions are made just before deployment, there may be insufficient time for brigade S-1s to
  work replacements before deployment. Below are common medical boards and programs that involve S-1s:
  * MOS Administrative Retention Review (MAR2). An administrative board authorized under AR
  635-40, Disability Evaluation for Retention, Retirement, or Separation, but not part of the
  Disability Evaluation System. It is held for Soldiers whose medical condition(s) are determined
  by the appropriate medical authority to meet the medical retention standards in chapter 3, AR
  40-501, Standards of Medical Fitness, but nonetheless require duty limitations necessitating a P3
  profile. The MAR2 evaluates whether the profile limitations prevent the Soldier from satisfactorily
  performing primary MOS or area of concentration duties in a worldwide field or austere
  environment. The MAR2 evaluation may result in retention in primary MOS or area of
  concentration, reclassification, or referral to the Disability Evaluation System.
  * Medical Evaluation Board. The Medical Evaluation Board is an informal process conducted IAW
  AR 635-40 which is phase 1 of the Disability Evaluation System. The designated medical authority
  refers Soldiers directly to the board when the Soldier has reached the medical retention
  determination point for a condition(s) that individually or in combination fails the medical
  retention standards of AR 40-501, chapter 3. Per AR 635-40, the Disability Evaluation System
  begins as of the earliest approval signature of the DA Form 3349 (Physical Profile); thus, a Soldier
  is in the system before the completion of the Medical Evaluation Board. When a MAR2 evaluation
  results in a referral to the Disability Evaluation System, the Soldier is in the system as of approval
  of the MAR2 decision. The Medical Evaluation Board cannot return a MAR2-referred Soldier to
  the Disability Evaluation System unless the board upgrades the Soldier’s profile to a P2 or P1, in
  addition to confirming the Soldier’s condition(s) meet medical retention standards.
  * Physical Evaluation Board. The Physical Evaluation Board is conducted per AR 635-40. An
  informal Physical Evaluation Board initially adjudicates all cases, which is essentially a paper
  board. In accordance with 10 USC 1214, no Soldier may be separated without a full and fair
  hearing if the Soldier demands one. The full and fair hearing is the formal Physical Evaluation
  Board. Board findings are not final until approved by the U.S. Army Physical Disability Agency
  for the Secretary of the Army. Certain cases require higher-level approval.
  * Warrior Transition Unit. Personnel undergoing medical care and rehabilitation may be assigned
  or attached to a warrior transition unit. Warrior transition units are for Soldiers with complex
  medical needs requiring six months or more of treatment or rehabilitation. Commanders must clear
  uniform code of military justice actions, other legal actions, investigations, property/hand receipt
  issues, and LOD determinations before transferring Soldiers to a warrior transition unit.
  * Community Based Warrior Transition Unit. The community based warrior transition unit
  functions as a warrior transition unit for Soldiers who receive medical care in their community at
  DOD or Department of Veterans Affairs health care facilities. Community based warrior transition
  units primarily provide outpatient care management and transition services for USAR and ARNG
  Soldiers who do not need day-to-day medical management provided by warrior transition units on
  Army installations. Community based warrior transition units perform command and control
