Watch FilmoFlix. Fourteen Marines and one Corpsman relive their journey from enlistment through the epic 77-day Siege of Khe Sanh during the Vietnam War. Just boys in 1968, they recount their ferocious experience in that wet and isolated battleground, fighting fear and the enemy only to return to a nation at odds with this controversial war. Still today, the Khe Sanh experience simmers just beneath their skin.
