Happened to see this movie recently - and lo and behold, the focal point was a sniper attack with a Galil. For reasons unknown, the hero was chambering a round before each shot, so it looked like a bolt action. Or his rifle was failing to cycle.
You need to check this one out; especially since benicio Del Toro is using a
.308 ARM (not no stinking 5.56) doing some serious damage. There is even a scene were there is a scope mounted on the rifle; in a sniper role :sniper
