### Second World War

[edit]

The document Amphibious Operations (Phib), Volume 19 titled Employment of Military Police and published in early 1945 (PHIB 19) provided a description of two basic Marine Corps military police organizations during World War II: the Fleet Marine Force military police battalion and the Marine division military police company.

The military police company organic to the Marine division possessed three platoons and a company headquarters. Company included approximately 100 Marines. The company commander also acted as the division provost marshal. Doctrinal provision existed for a division to request additional military police support from the next higher echelon of command when necessary.

Fleet Marine Force military police battalions, new organizations at the end of 1944, possessed four military police companies and a headquarters and service company. The first of these military police battalions was activated on 27 October 1944. These new battalions saw varying manning levels between 350 and 500 Marines. Doctrinally, one or more of these battalions was task organized into a force above the division level.[2]

After the war, military police battalions were deactivated.[citation needed]

### Vietnam War

[edit]

During Vietnam War, military police battalions were reactivated for the first time.[citation needed]

1st MP Battalion Marine guards the main bridges into Da Nang in 1969

On 28 May 1966 the 1st Military Police Battalion arrived at Da Nang, South Vietnam and relieved the 3rd Battalion, 3rd Marines from responsibility for the security of Da Nang Air Base.[3]

By 1968 the 3rd Military Police Battalion had joined the 1st MP Battalion at Da Nang and both units were under the control of Force Logistic Command/1st Force Service Regiment which provided logistic support to the 1st Marine Division and the South Korean 2nd Marine Brigade.[4]: 582  The 3rd MP Battalion operated the III MAF brig in Da Nang built to hold 200 prisoners. On 16 August 1968 a riot took place and the prisoners seized control of the brig for 2 days before being subdued by the MPs using tear gas.[4]: 566  In addition to brig duties, the 3rd MP Battalion furnished war dogs for the 1st Marine Division, staffed the III MAF Criminal Investigation Department and contributed a 50-man MP contingent to the U.S. Armed Forces Police (AFP) in Da Nang. Marines from this AFP detachment protected the U.S. Consulate in Da Nang and helped guard the POW ward at the U.S. Army's 95th Evacuation Hospital. Until 1 January 1970, the commander of the 3rd MP Battalion had the additional duty of III MAF Provost Marshal, as such, he had operational control of the AFP in Da Nang.[5]: 250

The 1st and 3rd MP Battalions fought in the defense of the Da Nang Vital Area in the Tet and Phase III offensives of 1968 and the Tet 1969 attacks.[4]: 145, 377 [6]

On 10 August 1970, as the 3rd MP Battalion prepared for redeployment in Operation Keystone Robin Alpha, the 1st MP Battalion assumed control of the Marine war dog teams and also took over the 3rd Battalion's security responsibilities in the Da Nang Vital Area.[5]: 250

In early 1971 the 1st MP Battalion was based at Camp Stokes near Da Nang AB.[5]: 245  On 7 May 1971, with the cessation of all Marine combat in South Vietnam, the battalion ended small-unit operations and turned defense of Da Nang AB over to the Army of the Republic of Vietnam 104th Regional Force Battalion and the 796th Regional Force Company. The battalion retained its AFP and brig duties throughout the rest of May, as well as guarding the remaining 3rd Marine Amphibious Brigade cantonments. On 5 June the battalion was released from all AFP tasks and the battalion stood down on 7 June. By 24 June all elements had departed for Camp Pendleton, where the battalion was deactivated.[5]: 252

In 1970-1971, military police battalions were deactivated again.[citation needed]

### War in Afghanistan

[edit]

Military police battalions were reactivated for the second time in 2010s according to the Marine Corps Bulletin 5400 as law enforcement battalions. There were 3 active duty (1st, 2nd, 3rd) and 1 reserve (4th) law enforcement battalions. Each battalion included 3 law enforcement companies and headquarters company which included military working dog platoon, detention security, medical platoon, criminal investigation platoon and battalion HQ.[1]

In 2016, Marine Corps organized own Military Police Officer Basic Course in Fort Leonard Wood, Missouri.[7]

### Modern times

In 2020-2021, all 3 active duty law enforcement battalions were deactivated as part of the Marine Corps’ Force Design 2030 plan.[8]
