Ca Lu Combat Base
Ca Lu Combat Base was a United States Marine Corps base located on Highway or Route 9, near Krông Klang, Đa Krông District, western Quảng Trị Province, South Vietnam.
Ca Lu was the western terminus of Highway 9 for the U.S. Marines since the road was cut between there and the Khe Sanh Combat Base. The 3rd Marine Division had overall command and control of the DMZ area.
