MCO 1300.8 - Marine Corps Personnel Assignment Policy

Scope

MCO 1300.8 with Admin Change 2 establishes Marine Corps personnel assignment policy. The order covers the full assignment lifecycle, PCS authorization and orders, inbound and outbound check-in and check-out, accountability, monitor coordination, billet assignment rules, reserve and active component assignments, and special-case assignments. Every PCS move, every unit join and detach, and every billet fill in the Marine Corps runs on rules from this order.

Audience

• S-1 officers, S-1 chiefs, adjutants, and IPAC inbound and outbound counselors executing joins, detaches, and orders.
• HQMC monitors and MMEA coordinating assignments against manning precedence.
• Commanders signing inbound and outbound packages and requesting replacements.
• Marines executing PCS, retirement, or separation moves.

Chapter map

Chapters the portal works from.

• Chapter 3. Monitor coordination. Replacement requests route to the monitor with operational justification, critical gaps escalate through the commander to MMEA.
• Chapter 4. Billet identification code management and internal assignments. Grade, MOS, date of rank, and special billet qualifications match the Marine to the BIC, with a documented exception-to-policy path for out-of-rules fills.
• Chapter 6 Section 13. OCONUS tour extension incentives. The OTEIP designation list, benefit elections, and required documentation for tour extensions, paired with special rest and recuperation absence elections.

Operative content

• The report date is the date on the PCS orders. The Marine reports on or before it. Late reporting without authorization is misconduct, and the gaining unit grants a delay or initiates UCMJ action.
• The MCTFS join sets the personnel record at the gaining unit, the detach closes it at the losing unit, and the detach effective date drives pay continuity and the gaining unit join.
• The EDFR is the reconciliation backstop. The IPAC pulls it within 24 to 48 hours of a join or detach and clears every rejection within 5 working days.
• Check-in and check-out run through the unit S-1 and every staff section, with the S-4 receipting individual gear. Outstanding gear at check-out creates indebtedness.
• Time-on-station requirements gate assignment incentives, including SLIP eligibility, and the order coordinates expedited transfer requests for SAPR victims.
