Khe Sanh

Khe Sanh Combat Base South Vietnam was in the corner of Quang Tri  Province 18 miles south of the DMZ and 8 miles east of Laos in   mountain terrain. The base was a blocking position to stop the North Vietnamese Army or NVA from moving men and supplys into the south along Route 9. An air strip for resupplying troops and for recon flights over the Ho Chi Minh trail.
 

Khe Sanh became the scene of a large offensive operation by the People's Army of Vietnam (PAVN, also known to many English speakers as the NVA and US Marines in 1968. The defense of the base was codenamed Operation Scotland. U.S. commanders provoked the battle hoping the PAVN would attempt to repeat their famous victory at Dien Bien Phu. The overwhelming power of US air support and vastly increased airlift capacity made this impossible.
