Mckinney – Cadence
I’m not 100% sure if Mckinney was even a drill sergeant in this movie but I put him in here anyway because he acted as such. Played by Martin Sheen, he’s a tough acting, big drinking military man who’s out to prove himself and to prove to Private Bean (Charlie Sheen) that he’s as good as anyone else.
Sgt. Cass – Renaissance Man
A very underrated role by Gregory Hines. Cass is trying to mold his recruits into soldiers while he’s at odds with Danny Devito’s character who is trying to educated these boys. Hines and Devito are constantly butting heads on whose philosophy is better. But you see that Hines has a compassionate side.

During the first incursion into the atmospheric processor, he enforced Gorman’s orders not to use pulse rifle and smartgun ammunition. Shortly after finding a still-alive cocooned colonist whose chest bursts to reveal an alien, Apone grabbed a flamethrower from Frost to incinerate it
