New Orleans -- Marine Administrative Message 234/16 lists several changes to the Marine Corps Personnel Assignment Policy for Reserve Component Marines.
One change mandates that Marines with a non-ground combat arms military occupational specialty transferring to ground combat arms units from the Selected Reserve or Active Component must pass a physical fitness test and a combat fitness test 18 months prior to projected join date and with scores that meet the unit assignment criteria.
A second change states that non-ground combat arms Marines transferring from the Individual Ready Reserve, or accessing from off-contract must meet the unit assignment criteria within 180 days of affiliation. Those who do not meet the criteria will be involuntarily dropped to the IRR or transferred to another unit.
