I do not wish to start foul natured arguments, but if this is a good natured debate, many modern sniper rifles can be armed with excessivly large (around the leghth of your hand an width of your thumb, with an explosive tiip that penatrates the armour and another that will go through it and hit the crewmember/ explosive.
*sigh* Cosmo: look up PTRS, PTRD, and about 15 different modern snioer rifles, Armour piercing round went straight through German Panther and Panzer tanks. they also were completely shredded by any explosive underneath them. fire o would warp the batrrel or explode the fuel tank, some bullet went straight through the tank, hitting an explosive or killling a crew member. This isn't calll of duty, man.
