Southern Comfort (1981), directed by Walter Hill
The story is set in 1973 Louisiana. A Louisiana National Guards squad is sent on a weekend exercise into the Bayou swamps. The eight men represent a variety of personalities the most interesting of which are Spencer, the intellectual cynic, and Hardin, the Texan survivalist and hater of redneck mentality. But it is the redneck macho mentality of some of their comrades, and their failure to respect the sensitivities of the local Cajun population, that ultimately gets the entire squad into deep trouble as they proceed through the wilderness of the swamps.
When reaching a river bed with no bridge or crossing in sight, the soldiers decide to 'borrow' some canues left at the river bed by Cajun trappers. Midway across the water, one of the soldiers pointlessly provocates the approaching Cajuns by shooting at them with blanks. This and subsequent mistakes made by the increasingly headless soldiers ultimately provoke a bloody and merciless response from the locals who decide to follow the intruders through the swamps and hunt them down.
