Understanding body armor levels
Body armor is rated based on the level of protection it provides against specific threats. The National Institute of Justice (NIJ) sets these standards, with Level IIA being the lowest and Level IV the highest. Level 4 body armor, also known as Level IV, is designed to stop armor-piercing rifle rounds, such as the .30-06 M2 AP.NIJ Level | Protection |
---|---|
Level IIA | 9mm; .40 S&W |
Level II | 9mm; .357 Magnum |
Level IIIA | .357 SIG; .44 Magnum |
Level III | Rifles up to 7.62x51mm NATO FMJ |
Level IV | Armor-piercing up to .30-06 M2 AP |
