Purpose printed on the form

Records voluntary extensions of enlistment into the U.S. Armed Forces. The completed form becomes a permanent part of the Marine's Enlisted Master File and Field Personnel File and files into the OMPF.

When Marines use it

The revision 10-16 form centers on medical extensions. Item 17 requires one of three attachments: a NAVMED 6100/5 for a temporary limited duty (TLD) extension, the Joint DoD IDES referral form for a referral into the Integrated Disability Evaluation System, or a Line of Duty benefits authorization letter. Extension terms run up to 6 months for TLD or 9 months for an IDES referral.

Completion rules from the instructions page

• Terms of enlistment and extension enter in both word and figure.

• The Marine signs full first, middle, and last name and executes the agreement before the Commanding Officer.

Routing and approval

Once effective, only CMC MMSR-4 or CMC WWR RMED cancels the extension, upon receipt of the PEB index to adjust PRR and EAS. Item 18 approval by CMC MMSR-4 or CMC WWR RMED applies only to second and greater medical extensions beyond the existing contractual EAS per MCO 1900.16 paragraph 8105.3. The reporting unit runs TTC 116 00 with EXTENL, months, and EXT entries, then files the form into the OMPF.
