The Unit Deployment Program (UDP) is a system for assigning deployments of the United States Marine Corps. To reduce the number of unaccompanied tours and improve unit continuity, the Commandant of the Marine Corps, (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 Fiscal Year 1987 (FY87) and FY88, Amphibious Assault Vehicle (AAV) companies and direct support artillery batteries were phased in and later, Light Armored Reconnaissance (LAR) companies were also included in the program. The Marine Corps’ objective is to adhere as closely as possible to a six-month period of deployment away from a unit's Continental United States (CONUS) home base. 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.
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 U.S. Department of Defense (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.
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 expiration of active service (EAS), permanent change of station (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 Marine Corps Total Force System (MCTFS) entries have a critical impact on unit staffing during the predeployment period. Erroneous or missing information will result in an excessive administrative workload and may contribute to reduced personnel readiness or key billet shortages.
In addition to the MCTFS data, Deployment Staffing Reports (DSRs) are used to facilitate proper assignment of deployable Marines. DSRs are addressed in detail via message traffic to deploying units possessing a dedicated MCC. A year prior to the scheduled deployment, HQMC (MMEA) issues an implementation message. 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 unit cohesion units receive staffing of their deployable Marines on a varied schedule (between 8–12 months prior to deployment) based on their fill window.
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 is payable to Marines in the grade of corporal or above upon permanent or temporary assignment to sea duty. Rates are based on the amount of sea duty accumulated by the Marine. Instructions concerning entitlement conditions are contained in Volume 7A, Chapter 18 of the Department of Defense Financial Management Regulation (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.
The Joint Travel Regulations (JTR) authorizes payment of standard or flat rate per diem, commonly referred to as deployed per diem, for members of units deployed overseas. The authority to determine rates for deployed per diem and the mechanics of their use has been delegated to the CMC by the Secretary of the Navy. 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.
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.
Since the Marine Corps does not have any chaplains or medical personnel, it relies on the Navy to provide this support. Navy personnel selected for assignment shall have an end of active obligated service (EOS) sufficient to complete the unit deployment plus one month for transition. All enlisted personnel assigned must be physically qualified to perform their required duties prior to deployment.
Force Reconnaissance (FORECON) are United States Marine Corps deep reconnaissance companies that supply military intelligence to the command element of the Marine Air-Ground Task Force (MAGTF). Force Reconnaissance companies, unlike USMC division reconnaissance, report to the Marine expeditionary force (MEF) and provide direct action and deep reconnaissance during large-scale operations.
A Sea Service Ribbon is an award of the United States Navy, U.S. Marine Corps, U.S. Coast Guard, the U.S. Army, and the NOAA Commissioned Officer Corps which recognizes those service members who have performed military duty while stationed on a United States Navy, Coast Guard, Army, or NOAA vessel at sea and/or members of the Navy, Marine Corps or Coast Guard who have been forward-deployed with their home unit.
An Overseas Service Ribbon is a service military award of the United States military which recognizes those service members who have performed military tours outside the borders of the United States of America. There are different versions of the Overseas Service Ribbons for the U.S. Army, U.S. Navy, U.S. Air Force, U.S. Space Force, and the U.S. Coast Guard. Both the U.S. Navy and the U.S. Marines receive the Navy and Marine Corps Overseas Service Ribbon.
The United States Navy Reserve (USNR), known as the United States Naval Reserve from 1915 to 2005, is the Reserve Component (RC) of the United States Navy. Members of the Navy Reserve, called Reservists, are categorized as being in either the Selected Reserve (SELRES), the Training and Administration of the Reserve (TAR), the Individual Ready Reserve (IRR), or the Retired Reserve.
Earl Edward Anderson was a U.S. Marine four-star general. He was the youngest active duty Marine ever promoted to the rank of general and the first active duty Marine Naval Aviator to be promoted to a 4-star rank. He became Assistant Commandant of the Marine Corps on April 1, 1972. He was promoted to general on March 31, 1972. General Keith B. McCutcheon had been promoted to four-star rank the day of his retirement for medical reasons on July 1, 1971. During his 35-year Marine career, he served in combat actions in World War II, the Korean War, and the Vietnam War.
The Officer Qualification Record (OQR), NAVMC 123a, is one of the best sources of information concerning US Marine officers. It is similar to the enlisted Service Record Book (SRB) with only minor differences. This "record presents a cumulative and concise summary of basic events in the officer's career from the time of acceptance of appointment to separation. The OQR also serves as the basis for reporting information into the Marine Corps Total Force System and provides commanders with background information to assist them in officer personnel planning and assignment."
Wallace Martin Greene Jr. was a United States Marine Corps four-star general who served as the 23rd Commandant of the Marine Corps from January 1, 1964, to December 31, 1967.
The Headquarters Marine Corps (HQMC) is a headquarters staff within the Department of the Navy which includes the offices of the Commandant of the Marine Corps, the Assistant Commandant of the Marine Corps and various staff functions. The function, composition, and general duties of HQMC are defined in Title 10 of the United States Code, Subtitle C, Part I, Chapter 506.
William D. Catto is a United States Marine Corps major general who is the chief of staff of the United States European Command. He assumed the post in July 2006, becoming the first U.S. Marine to hold the role. Catto has served over 10 years in command assignments at the lieutenant colonel, colonel, brigadier general, and major general ranks.
The Marine Corps Systems Command (MCSC) is the acquisition command of the United States Marine Corps, made up of Marines, sailors, civilians and contractors. As the only systems command in the Marine Corps, MCSC serves as Head of Contracting Authority and exercises technical authority for all Marine Corps ground weapon and information technology programs.

Ronald S. Coleman is a former United States Marine Corps officer. Coleman, advanced in rank to lieutenant general on October 27, 2006, became the second African-American in the Marine Corps to reach the 3-star rank.
The United States Marine Corps' Judge Advocate Division serves both to advise the Commandant of the Marine Corps (CMC) and other officials in Headquarters, Marine Corps on legal matters, and to oversee the Marine Corps legal community. The head of the Judge Advocate Division (JAD) is the Staff Judge Advocate to the Commandant.
Religious Program Specialist (RP) is a designated rating within the United States Navy. As an essential member of Professional Naval Chaplaincy, RPs fulfill a crucial function in administering religious ministry within the Department of the Navy (DON). Together with chaplains, they form the Religious Ministry Team (RMT). In this capacity, RPs actively support the provision and facilitation of Religious Ministry, offering assistance and care to Navy and Marine Corps personnel, as well as their families, irrespective of their backgrounds and faith affiliations. Despite working in a religiously diverse environment, RPs are not mandated to hold religious beliefs nor perform pastoral counseling for the service members under their care. Due to the mobile nature of the units they may be assigned to, RPs can be stationed on Navy ships, at various Navy and Marine Corps commands, navy construction battalions, and other unique combatant units-rendering them globally deployable.
The structure of the United States Navy consists of four main bodies: the Office of the Secretary of the Navy, the Office of the Chief of Naval Operations, the operating forces, and the Shore Establishment.
Marine Corps Total Force System (MCTFS) is the integrated pay and personnel system for active duty and reserve Marines, and the authoritative source of data for all Marine Corps (MC) pay and personnel information consisting of over 550,000 records. MCTFS has been successfully fielded and is currently in the post-deployment system support phase of its lifecycle. MCTFS supports centralized business-critical pay functions for the Marine Corps Enterprise on time and accurately, including computation and payment of net pay to individual Marines, while accommodating all necessary system change requests to meet current legislative, regulatory, mission essential, force reset, and contingency change requirements. MCTFS is maintained in an audit compliant state to ensure accurate financial transactions and reporting. MCTFS includes a comprehensive history of pay entitlements, deductions, and payments for each active duty and reserve Marine. The principal advocate within the Marine Corps is the Deputy Commandant, Manpower and Reserve Affairs.
Operation Gyroscope was a United States Army program implemented between 1955 and 1959 during the Cold War that modified the system of troop rotation, so that entire divisions were rotated out of overseas service together, rather than individual soldiers. The program also applied to smaller non-divisional units, and was primarily used to exchange units between the United States and units in Germany under United States Army Europe. The system aimed to increase retention rates by boosting morale and unit cohesion with the added incentive of improving military family stability through keeping soldiers together for most of their careers. The program initially increased morale, but the Army was unable to keep its promises to soldiers and thus the expected benefits failed to materialize, resulting in the early termination of the program after just one of the planned-three year rotation cycles had been completed.
Marine expeditionary unit (special operations capable) (MEU(SOC)) is a program created by the United States Marine Corps (USMC) and the United States Navy (USN) in 1985 for Marine expeditionary units (MEU). The program enhances MEUs providing them with additional training and equipment to become certified as special operations capable with a Maritime Special Purpose Force (MSPF). The designation special operations capable is unique to the Marine Corps and means in relation to special operations. The role of a MEU(SOC) however is not equivalent to the special operations role of special operations forces. Although considered special operations capable a MEU(SOC) does not form part of the United States Special Operations Command (USSOCOM) established in 1987 or the United States Marine Forces Special Operations Command (MARSOC) later established in 2006.
The Marine Corps Career Retention Specialist is an enlisted Marine who is responsible to the immediate Commanding Officer for all aspects of retention of enlisted personnel in the United States Marine Corps.
