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.

HMLA-775 conducts pre-flight maintenance
U.S. Marines with Marine Light Helicopter Attack Squadron (HMLA) 775, Marine Aircraft Group 41, 4th Marine Aircraft Wing, Marine Forces Reserve, conduct pre-flight maintenance during Integrated Training Exercise (ITX) 4-22 at Marine Corps Air Station Camp Pendleton, Calif., July 29, 2022. 4th Marine Aircraft Wing squadrons, including HMLA-775, Marine Medium Tiltrotor Squadron 764, Marine Fighter Attack Squadron 112, Marine Aerial Refueler Transport Squadron 234, and Marine Wing Support Squadron 473, worked side-by-side to execute an Expeditionary Advanced Base Operations scenario during ITX 4-22. MAG-41 tripled the combat radius of the AH-1Z Viper and UH-1Y Venom via multiple refueling methods, including the first use of the Tactical Aviation Ground Refueling System during an exercise by the Reserve Component. This vastly reduced the refueling time required and prevented MAG-41 personnel and aircraft from being targeted by the enemy. This scenario was carried out entirely by MAG-41 assets and demonstrated the Reserve Component's capability to execute missions described in Force Design 2030. (U.S. Marine Corps photo by Lance Cpl.
