D Troop 4th Cav - Hunter-killer Team W Aircraft T Shirt, Various, Classic, Black

D Troop, 4th Cavalry Regiment, was known for its "hunter-killer" teams during the Vietnam War. These teams combined helicopters—typically scout helicopters (OH-6A Cayuse or "Loach") and attack helicopters (AH-1 Cobra)—to locate and engage enemy forces. The scout helicopter would identify targets, while the attack helicopter would provide heavy firepower to neutralize them. This tactic was highly effective in reconnaissance and combat operations.
