History • Humans have been protecting themselves for thousands of years. • As the discovery of how to forge metals came, so did the advancement in body armour. • Firearms are invented. Body armour becomes obsolete. • Kevlar is invented and body armour makes its return.
Kevlar • Kevlar was invented by accident. • Ten-thirty layers of kevlar are usually used to stop a bullet. • Kevlar is very lightweight and flexible. • Kevlar often causes blunt trauma which can be fatal. • Most kevlar only protects against low velocity firearms.
Limited Protection • All vests only offer limited protection. • Many vests come with ceramic inserts. • Many vests will do nothing to stop a high powered rifle round. • Mobility of the person is a necessity. • Concealment of the vest is also very important.
Armour in the World Wars • Armour did not play a significant role in either of the World Wars. • Helmets were basically the only protection that solders had. • Flak jackets were worn by aircrews.
Current Armour being used • The Americans are using the interceptor vests. • The Canadian Forces are using fragmentation vests. • Most enemies faced by the American’s have no protection at all. • Some special forces units use elite body armour that costs a lot of money.
In Development • There are a couple of types of body armour currently in development, or are not yet widely known. • Liquid Body armour is one of these. • Dragon Skin is another.
Helmets • Most major armies are issued a kevlar helmet. • Can stop low velocity firearms and shrapnel. • Can deflect high velocity rife rounds.
