, (CMC) established it 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. The program commenced in October 1977 and has proceeded through the six phases. In August 1985, tank companies began phasing into the program but following Southwest Asia, were discontinued. In

In the case of Hawaii-based infantry battalions, which employ a three-battalion rotation base, a seven-month period of deployment is executed to support the Unit Cohesion Program and efficient staffing of first term Marines. It must be understood, however, that shipping or airlift schedule variations, and exercise or contingency operations will occasionally necessitate longer or shorter deployments for participating units. It is imperative that all personnel involved in these deployments be kept fully informed of planned deployment duration and subsequent deployment schedule changes.


Assignment and distribution

The UDP is an alternate method of meeting the Marine Corps’ manpower commitment. CMC has directed that the Deputy Commandant for Manpower and Reserve Affairs is responsible for the assignment of company grade officer and enlisted personnel into all units participating in the UDP. This responsibility is exercised through a series of monitored command codes (MCCs). This centralized control of assignments is in keeping with

(DoD) directives concerning individual assignments for Marines and the operational requirement for uniform staffing. Concurrent with the assumption of this responsibility is the requirement to establish standing operating procedures to provide coordination between Headquarters, U. S. Marine Corps (HQMC) and operational force commands concerning manpower-related matters in deploying units.


Staffing

A key difference between command staffing and unit deployment staffing is the requirement to stabilize a unit's personnel for the duration of the deployment. Assignment efforts must identify replacements for Marines who cannot participate in the deployment either because of

(PCS) orders, or other circumstances. The important difference for the deploying unit is that, while these Marines are chargeable, they are non-deployable and therefore, must be replaced. The point at which the deployable versus chargeable distinction is made occurs, at a minimum, six months prior to embarkation; however, most assignments are initiated six months prior to the estimated date of arrival. Consequently, assignment monitors at HQMC will begin to measure unit deployment strengths as early as one year prior to deployment. Even though most assignments will be identified closer, commanders must recognize that deployment-related

This message explains the DSRs, establishes staffing targets, sets "lock-on," identifies predicted entry-level school graduate arrivals, and directs submission of a monthly DSR to HQMC (MMEA-12). This report establishes a dialogue that ensures staffing of the unit by lock-on, a date when a unit has received full staffing with deployable Marines. Synchronized

units receive staffing of their deployable Marines on a varied schedule (between 8–12 months prior to deployment) based on their fill window.


Pay entitlements while on UDP

While Marines are deployed, they could be entitled to several monetary entitlements to help in offset the expense of being deployed, especially for those with families.


Career Sea Pay

Career sea pay is payable to Marines in the grade of

(DoDFMR). Career sea pay is composed of two elements, history and pay, which are computed on a 30-day month basis. MCO P1080.40 outlines the unit diary reporting requirements for career sea duty history and career sea duty pay.


Deployed Per Diem

. MCO 7220.39, Standard/Flat Rate Per Diem Allowances, implements the deployed per diem allowances for UDP units. Deployed per diem rates are published by HQMC semiannually via MARADMIN message (MCBul 7220). Funding responsibility for deployed per diem resides with HQMC(MP). MCO P1080.40 contains procedures and MCTFS reporting requirements for commencement, termination, and adjusting the entitlement to deployed per diem.


Family Separation Allowance (FSA)

FSA-Type II provides compensation for added expenses incurred because of enforced family separation due to a Marine's assignment. Volume 7A, Chapter 27 of the DoDFMR defines FSA-Type II eligibility requirements. MCO P1080.40 contains unit diary reporting requirements for the FSA-Type II allowance.
