Philippine Department

The Philippine Department (Filipino: Kagawaran ng Pilipinas/Hukbong Kagawaran ng Pilipinas) was a regular United States Army unit whose mission was to defend the Philippine Islands and train the Philippine Army. On 9 April 1942, during World War II, the unit surrendered to the Japanese. The Department and its sub-units were predominantly under the command of American officers, including an American general, while the majority of the troops were enlisted Filipinos, known as the Philippine Scouts (PS). The primary force of this Department was the Philippine Division. Of the 22,532 troops, 10,473 were members of the Philippine Division itself.

This unit was formally organized in 1913 and, on 26 July 1941, was attached to US Army Forces – Far East (USAFFE). Following the creation of USAFFE, the Philippine Department became, in effect, a corps area service command. Tactical command was thenceforth under USAFFE's control.

Patch of the Philippine DepartmentEdit

All units of the Department wore the Philippine Department shoulder sleeve insignia, with the exception of the Philippine Division, which wore their own patch: a golden carabao on a red shield.

Officially, the Philippine Department’s insignia featured the Philippine Sea Lion, in white, superimposed on a blue oval with a height of 2.5 inches. The Sea Lion is derived from the coat of arms of Manila. The Philippine Department and Philippine Division insignia were both approved on 8 July 1922.
