320 Division (Vietnam)
During the Vietnam War it was a well trained division of the North Vietnamese Army that operated in the DMZ area of South Vietnam. The division battled U. S. Marines in and around Đông Hà and Leatherneck Square. One of the major battles the unit was involved in was the Battle of Dai Do northeast of Đông Hà. This battle was costly to both sides.
Today it is part of the 3rd Corps (Vietnam People's Army).
