In the Line of Duty: The F.B.I. Murders(1988)

Overview:

It is 1985, and a small, tranquil Florida town is being rocked by a wave of vicious serial murders and bank robberies. Particularly sickening to the authorities is the gratuitous use of violence by two “Rambo” like killers who dress themselves in military garb. Based on actual events taken from FBI files, the movie depicts the Bureau’s efforts to track down these renegades.
