1968 Tunnel Rats

In Tunnel Rats a special US combat unit is sent on a mission to search and destroy Viet Cong resistance forces in the endless networks of tunnels in the jungles of Vietnam. Armed with only handguns, flashlights and knives the men soon find themselves embroiled in hand- to-hand combat. As the battle moves underground, for both sides, the struggle becomes less about winning than about survival.
