According to the Geneva Convention, soldiers are not allowed to use a 50 cal. Machine gun to shoot at personel. It is allowed to be used against vehicles and other equipment. If you were a private from Hoboken NJ and you were manning the 50 cal. machine gun in the turret of a Army truck in a 3 truck convoy and you suddenly came under attack would you use the 50 cal on personel. If your route was blocked and 100 screeming Iraqie Jihadist were coming at you weapons blazing and molitov cocktails in hand (a gas and bottle bomb), and they are getting ready to launch the rocket propelled grenade at you, would you duck back into the truck and get your M16 (which has a very small round and only 20-30 rounds of ammo per mag), or would you lock and load the 50 cal. (which has a very large bullet and a 200 plus ammo belt)and mowe the enemy down in violation of the genevia convention.
