from what i remember a military man is suicidal, there’s a scene with him having a shotgun? in his mouth but then decides to turn rogue and blows up the base. scenes i remember also include him hiding in a closet in a girls office, i think he breaks the neck of an unsuspected visitor while in the office and puts bombs on a plane to blow it up.

Can you recognise it from this list? (Maybe you could recognize the actors from the cover.)
