DET 1 GAR TRP COMD 4th USARMY

**DET 1, GAR TRP, COMD, 4th US Army** was a detachment unit operating under the 4th United States Army, which was established in 1932 and played a key role in training and continental defense during World War II and the Cold War. The designation "GAR TRP" likely refers to a "Guard Troop" or similar security element, responsible for installation security, ceremonial duties, or rapid response within the command structure. As part of the 4th Army's headquarters or command group, DET 1 provided essential support, logistics, and operational security for higher command functions. The unit contributed to the readiness and effectiveness of the 4th US Army until the Army was inactivated in 1971, after which many of its functions were absorbed by other commands.
