The Philippine Scouts (Filipino: Maghahanap ng Pilipinas or Hukbong Maghahanap ng Pilipinas) was a military organization of the United States Army from 1901 until after the end of World War II. These troops were generally Filipinos and Filipino-Americans assigned to the United States Army Philippine Department, under the command of American commissioned officers (though a handful of Filipino Americans received commissions from the United States Military Academy). Philippine Scout units were given the suffix "(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 Army led at that time by General Emilio Aguinaldo. In 1919–1920, 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.
