The Philippine Scouts was a military organization of the United States Army from 1901 until the end of World War II. Made up of Filipino-Americans assigned to the United States Army Philippine Department, these troops were generally enlisted and under the command of White-American officers, however, a handful of Filipino Americans received commissions from the United States Military Academy. Philippine Scout units were given a suffix of (PS), to distinguish them from other U.S. Army units.
The first Scout companies were organized by the US in 1901 to combat the Philippine revolutionary forces led at that time by General Emilio Aguinaldo. In 1919–20, the PS companies were grouped into regiments as part of the US Army and redesignated the 43d, 44th, 45th, and 57th Infantry Regiments, plus the 24th and 25th Field Artillery Regiments, the 26th Cavalry Regiment (PS) and the 91st and 92nd Coast Artillery Regiments. Service and support formations were also organized as engineer, medical, quartermaster and military police units. The infantry and field artillery regiments were grouped together with the U.S. 31st Infantry Regiment to form the U.S. Army’s Philippine Division. At this point, the Scouts became the U.S. Army’s front line troops in the Pacific.
