Body armor is designed to stop most intermediate threats but is not specifically rated to stop a .50 caliber bullet.
We stack multiple plates of level four armor, which is designed to stop armor-piercing rounds.
We conduct the test with a .50 cal sniper rifle and various types of ammunition, including armor-piercing incendiary explosive rounds.
The .50 cal round easily penetrates the armor, causing significant damage.
Stacking more plates does not provide effective protection against a .50 cal bullet.
