I watched a documentary about body armor and helmet recently. It showed everyone how a WWII rifle bullet can easily go through both sides of a modern helmet of U.S. army. Although the shooter stood only maybe 30 feet away from the helmet, it did go through (both) sides. That pretty much mean no helmet in the world can withstand a high power rifle bullet's direct hit from relative short distance. So why do you think the military still spending tons of money to equip every soldier with helmet and body armor? If these heavy gears can't really protect them from real danger?
