Dragon skin bulletproof vest repels AK-47 rounds
These bulletproof vests are the first to stop armor piercing rounds without using some bulky plate. They work better than traditional shit beat cops use because the fibers are woven tighter; and they're woven in a way that actually tightens up the weave upon impact by bullet or blade. They're soft enough to roll up into a ball, and are certified for dives, so they're appropriate for amphibious missions.
