Mission Dynamo (1989)

The Vietnam war and terrorists led by Torosky battle it out with South Vietnamese forces assisted by the American Army. For squad leader Merlin and PFC Bill, the war has become so meaningless that they don't care anymore. Seeing their friends die, they decide to desert and soon discover that there is no sanctuary in the jungle. It's only a matter of time before Torosky catches up with them.
