4601. UNSATISFACTORY PARTICIPATION

1. Members Serving Pursuant to the Initial Enlistment Agreement. When a Reservist with a mandatory participation requirement acquires at least nine unexcused absences within the preceeding 12-month period, or is categorized as an unsatisfactory participant for reasons other than excessive absences, the unit commander must pursue one of the following actions:

For example, sixteen missed drills divided by four equals a four month extension (16/4 = 4). Fractions equal to or greater than 1⁄2 of a month are rounded up. Lesser fractions are disregarded.

(2) Extensions will not be granted for periods of less than one month.

(3) This opportunity will only be afforded once in a Marine’s career.

(4) At no time will an extension exceed a Marine’s ECC.

(5) COMMARFORRES or its MSCs are the approval authority for all requests. Units not under the command of one of the MSCs will forward requests directly to COMMARFORRES (G-1) for approval.
