Detached Guard Co PI

**Detached Guard Co PI** (Presumably "Philippine Islands") was a specialized military unit established during the American colonial period in the Philippines, primarily under the United States Army. Activated to provide security for critical installations, supply depots, and communication lines, the company was typically composed of both American and Filipino soldiers. Its members were often detached from larger regiments, operating semi-independently in scattered locations across the archipelago. The unit played a key role in counterinsurgency operations against Filipino revolutionaries and later in maintaining order and protecting U.S. interests during the early 20th century. Over time, as the security situation evolved, the need for such detached guard companies diminished, leading to their eventual disbandment or absorption into larger formations.
