Replying to This is pissing me off

one of those things that you know but you just cant think of the name. alright its a movie, jungle setting, its like pouring down rain. theres that black drill sargent and they go through a training mission. the guy(drill sargent) gets shot and then no one knows who did it and it has tons of flashbacks and it jumps around everywhere, very confusing but a greaaat movie. oh yeah its got like the 8-ball i think, and talks about the traitors and all that stuff. does anyone know the name? gaaah this pisses me off so much---thanks yoo
