Sniper (1993)

Tough guy Thomas Beckett is a US Marine working in the Panamanian jungle. His job is to seek out rebels and remove them using his sniper skills. Beckett is notorious for losing his partners on such missions. This time he's accompanied by crack marksman Richard Miller, who's more of an office-type. Together they plan to seek out an important rebel leader, whilst avoiding a rogue marksman who frequents this part of the jungle.
