(1) Bulletproof vests are modern light armor specifically designed to protect the wearer’s vital organs from injury caused by firearm projectiles. Experimental inquiry into effective armor against gunfire continued, most notably during the American Civil War, World War I, and World War II, but it was not until the plastics revolution of the 1940s that effective bulletproof vests became available to law enforcers,military personnel , and others. The vests of the time were made of ballistic nylon and supplemented by plates of fiber -glass, steel, ceramic,titanium, Doron, and composites of ceramic and fiber glass, the last being the most effective.
