A bulletproof vest is an item of personal armor worn on the torso that absorbs the impact from firearms projectiles and explosion shrapnel. These vests are made from layers of woven or laminated fabrics and provide protection to the wearer from small-caliber handgun and shotgun projectiles. It is also provide protection against small fragments from explosives such as hand grenades.
Hard armour plates can be used with armour vest, for augmenting the protection level as the metal or ceramic plates provides additional protection from rifle rounds. Also metallic components or woven fiber layers make soft armor resistance to stab and slash attacks from knives or any similar weapons. Personal armour is commonly worn by army person, law enforcement officers, swats, squads, police forces, private citizens, security guards, and bodyguards etc. However, hard-plates reinforced vests are mainly worn by combat soldiers, police tactical units, and hostage rescue teams.
Modern body armor may combine a ballistic vest with other items of protective items, such as bulletproof helmets. Especially designed vests for police and military use may also include ballistic shoulder and side protection along with additional pouches. Bomb disposal teams and members wear heavy armor suit and helmets with visors for face protection and spine protection.
Today new fibers are discovered which are used for today’s modern generation of concealable body armor possible. The National Institute of Justice or NIJ initiated a research program for the development of lightweight body armor so that a policeman or officer could wear full time and do his duty without any problem. This program has identified new materials that could be woven into a lightweight fabric with great ballistic resistant properties.
