The siege against humanity

You all decide that the better thing to do is to give them cover fire as they are running towards the tower, you drop off the ammunition and speed away towards the tower, you hop out of the buggy and grab a gun from the trunk, you take a machine gun, you set it up behind a support pillar for extra cover and let it rip, your shooting blindly into the trees where the bullets are coming from, but you hear a cry of pain, the man that helped you with the ammo was shot and bleeding out, you can't just let him die slowly, but then again, you could die slowly with him.
