B:159th Avn(ASH)

B Company, 159th Aviation Battalion (Assault Support Helicopter), known as B/159th Avn(ASH), was a key U.S. Army aviation unit formed during the Vietnam War. Activated in the late 1960s, the company operated CH-47 Chinook helicopters, providing heavy-lift and logistical support for combat operations throughout South Vietnam. B/159th Avn(ASH) played a critical role in resupplying forward bases, airlifting artillery, and conducting troop movements under hazardous conditions. The unit continued its distinguished service in subsequent decades, supporting various missions until its inactivation as part of Army aviation restructuring.
