On the first mission (after the training one) you man a Browning .50 caliber on top of a Humvee. As you start out, you are in a village and begin driving, you can shoot anything in the village, and it won't kill them, so no innocent or friendly casualties. Also from the village to the convoy you can shoot your own men, even shoot the men in the broke down convoy, but when you get out of the Humvee, everything can die
