Bullet-Proof Armor

The strength of bullet-proof armor is classified into 4 categories, with NIJ Level 1 the weakest and Level 4 the strongest. However the Level 4 weights 26lb and seriously hinders the movements of the users. Currently the SDU officers use the British-made Highmark NIJ Level 3 armor with custom-made non-detachable pockets and shotgun-round holders. The armor guarantees users to have protections against 7.62 x 39mm rounds fired from the AK-47, which is considered as the most common rifle used by criminals in Hong Kong.
