A flak jacket or flak vest is a form of body armor designed to provide protection from case fragments ("frag") from high explosive weaponry, such as anti-aircraft artillery ("flak" a German contraction for "Fliegerabwehrkanone" (aircraft-defense gun)), grenades, some round shot used in shotguns and land mines and other lower-velocity projectiles. It is not designed to protect against bullets fired from small-arms such as rifles or handguns. However, certain flak jackets are able to sustain certain gunshots, dependent on the armor, the gun, and the distance that the bullet has travelled.
