Battle of Ia Drang
The Battle of Ia Drang (Vietnamese: Trận Ia Đrăng, [iə̯ ɗrăŋ]; in English ) was the first major battle between the United States Army and the People's Army of Vietnam (PAVN), as part of the Pleiku campaign conducted early in the Vietnam War, at the eastern foot of the Chu Pong Massif in the central highlands of Vietnam, in 1965. It is notable for being the first large scale helicopter air assault and also the first use of Boeing B-52 Stratofortress strategic bombers in a tactical support role.
