Weighing only fifteen pounds, a laminated steel jacket designed as the suit of armor for modern soldiers has stopped bullets from a submachine gun and from a German Mauser pistol fired at a twenty- five-yard range. With a solid sheet of heavy steel instead of the laminated steel and rubber, the jacket would weigh twenty-one pounds and would withstand high-power rifle fire, the inventor says. Three layers of steel 25/1,000 of an inch thick are used in front, two layers in back, separated by narrow strips of rubber.
