In April 1972, Troop H/10th Air Cavalry was formed (with assets from the disbanding Troop C, 7th Squadron-17th Cavalry Regiment) and placed under the 17th Aviation Group at Pleiku. The troop was located at Lane Army Airfield near An Son (14 km west of Qui Nhơn in Bình Dinh Province). H Troop aircrews conducted aerial reconnaissance, hunter/killer, and search & destroy missions using OH-6 Cayuse (Loach), AH-1 Cobra (Snake), and UH-1 Iroquois (Huey) helicopters and ground troops from the Republic of Korea's 2nd Infantry Division and the various South Vietnamese Army units. The unit disbanded shortly after the Paris Peace Accords were signed in 1973. Specialist 4 Robert Frakes, the last American combat casualty of the Vietnam War, perished in a post-crash fire after his OH-6 helicopter was lost to enemy fire on January 26th - the last day of US combat operations.
