ABOUT 

To reduce the number of unaccompanied tours and improve unit continuity, the Commandant of the Marine Corps (CMC) established UDP to provide for the deployment of units to the Western Pacific (WESTPAC) for periods of approximately six months. The initial program was a six-phased evolution that sequenced infantry battalions and aircraft squadrons/detachments into WESTPAC deployments, thus eliminating the 12-month permanent change of station assignments for personnel assigned to these units.
