Unit Responsibilities and LIMDU Re-Evaluation - S-1 Procedural Page

Role and responsibility

The unit commander owns LIMDU compliance per MCO 1900.16MCO 1900.16 Chapter 8 paragraph 8110 (Limited Duty Responsibilities). The S-1 chief tracks every Marine on LIMDU, PLD, EPLD, or light duty against the re-evaluation gate. The S-1 officer signs by direction on the routing of LIMDU transactions. The IPAC outbound counselor cuts the duty status transaction in MCTFS through UD-MIPS per MCTFSPRIUMMCTFSPRIUM. The medical treatment facility (MTF) commander signs the medical determinations. The Marine reports to medical appointments and complies with the duty restrictions. The legal advisor supports DES referral cases.

Source documents flow from the unit LIMDU roster, the medical appointment schedule, the MTF medical board package, the LIMDU duty status entry transaction, the re-evaluation gate appointment, the Page 11 entries per MCO P1070.12KMCO P1070.12K Chapter 6, the fit-for-full-duty return memo, and the DES referral package when warranted per Chapter 8 Section 2. Outputs include the maintained unit LIMDU roster, the documented re-evaluation appointments, the MCTFS duty status transactions, the Page 11 entries, the commander brief, the fit-for-full-duty return, and the audit trail for IGMC inspection.

Per Chapter 8 paragraph 8110 (Limited Duty Responsibilities), the unit, the IPAC, the MTF, and the Marine each carry defined duties through the LIMDU period. The unit tracks the Marine. The IPAC cuts transactions. The MTF re-evaluates. The Marine reports to appointments and complies with restrictions.

Trigger events

• New LIMDU, PLD, EPLD, or light duty case opens.
• Re-evaluation gate approaches.
• LIMDU period extension request from the MTF.
• Fit-for-full-duty return determination.
• DES referral triggered by PEB-warranting findings.
• Monthly LIMDU posture brief to the commander.
• New LIMDU coordinator at the unit triggers training.
• Annual IGMC inspection preparation cycle.

Processing workflow

1. Track Marines on LIMDU. The S-1 chief maintains the unit LIMDU roster with the duty status, the start date, the re-evaluation date, the medical scope, and the duty restrictions.
2. Monitor re-evaluation gates. Per MCO 1900.16MCO 1900.16 Chapter 8 paragraph 8110, the unit tracks the re-evaluation appointment cycle. Standard LIMDU re-evaluates at 6 months. PLD and EPLD re-evaluate annually.
3. Coordinate medical appointments. The unit ensures the Marine reports to scheduled medical appointments. The S-1 documents attendance.
4. Cut MCTFS transactions. Per Appendix E and MCTFSPRIUM, the IPAC cuts the duty status transaction on entry, change, and closure. The transactions flow through UD-MIPS.
5. Document on Page 11. Per MCO P1070.12KMCO P1070.12K Chapter 6, cut a Page 11 documenting the duty status action.
6. Brief the unit commander. The S-1 officer briefs the commander monthly on the unit LIMDU posture: total count, re-evaluation status, fit-for-full-duty returns, and DES referrals.
7. Coordinate fit-for-full-duty return. On a medical officer fit-for-full-duty determination, the unit closes the LIMDU status in MCTFS, cuts a closing Page 11, lifts the duty restrictions, and updates the unit roster.
8. Coordinate DES referral. Per Chapter 8 Section 2 paragraphs 8201-8208, the MTF refers PEB-warranting cases to the Disability Evaluation System. The unit and the IPAC support the referral.
9. Maintain LIMDU coordinator training. The S-1 chief trains new LIMDU coordinators on the responsibilities, the MCTFS transactions, and the Page 11 rules.
10. Run IGMC inspection preparation. The unit prepares the LIMDU file, the Page 11 entries, the medical appointment records, and the re-evaluation tracking for the IGMC FA inspection.

Systems of record and forms

Systems

• Marine Corps Total Force System (MCTFS). Master record holding LIMDU duty status.
• UD-MIPS. Cuts duty status transactions per Appendix E.
• Unit LIMDU Roster. Local register tracking the duty status, the start date, the re-evaluation gate, and the medical scope.
• MTF Records. Hold the medical board packages and the re-evaluation records.
• IGMC Inspection Preparation File. Holds the audit trail.

Forms

• Unit LIMDU Roster. Local format.
• Re-Evaluation Appointment Memorandum. Per paragraph 8110.
• Fit-for-Full-Duty Return Memorandum. Local format documenting the return.
• NAVMC 118 (11) Administrative Remarks. Page 11 documenting LIMDU actions per MCO P1070.12K paragraph 4006.
• Monthly LIMDU Posture Brief. Local format to the unit commander.

Common pitfalls

• Re-evaluation gate missed. Per Chapter 8 paragraph 8110, the unit tracks the gate. A missed gate breaks the LIMDU validity.
• Unit LIMDU roster out of date. The roster reflects current duty status. Stale roster entries break tracking.
• MCTFS transaction skipped on entry, change, or closure. Per Appendix E and MCTFSPRIUM, every duty status action cuts a transaction.
• Page 11 omitted on duty status action. Per MCO P1070.12K paragraph 4006, every action records on Page 11.
• Monthly LIMDU posture brief skipped. The commander loses visibility on the unit posture.
• Fit-for-full-duty return processed without medical officer determination. The medical officer determination drives the return.
• DES referral skipped on PEB-warranting findings. Per Chapter 8 Section 2 paragraphs 8201-8208, the MTF refers PEB-warranting cases.
• LIMDU coordinator change without training handoff. The new coordinator inherits the responsibilities without the system knowledge.

Decision points

• Re-evaluation timing. Per paragraph 8110, standard LIMDU re-evaluates at 6 months. PLD and EPLD re-evaluate annually. Light duty re-evaluates at the medical officer's defined gate.
• Fit-for-full-duty return versus extension versus DES. The MTF medical officer recommends. The unit commander approves within the policy and the medical scope.
• Monthly versus quarterly commander brief cadence. The unit commander sets the cadence based on the LIMDU population size. Larger populations support monthly briefs.
• IGMC inspection preparation scope. The S-1 chief weighs the IGMC FA Checklist items against the unit LIMDU file.
