I gotta go with Tom Berringer (as Barnes in Platoon).
I will always remember him as Barnes.
The part that freaked me out was when his unit was out on patrol. They stopped, and each soldier spaced themselvs out in order to maximize their ambush area's space. As they stood in their position, The black dude (I think his name was Manny) just vanished. Barnes & crew found Manny's cigarette still burning, but he was gone. Very erie. The Viet Kong had snuck in and grabbed him.
They later found Manny dead, tied to a tree a 1/2 mile down the trail. Barnes just stood there.... And said "those.... M#ther-F#cker's"
The marines went to a nearby village and Barnes started executing civilians. Then Burned the village down. That event led him to murder a co-marine that disagreed with his actions.
