Hard body armor provides the most protection from the widest range of firearms. While soft body armor can protect against a range of handguns, hard armor plates are the most effective defense against high-powered rifles and armor-piercing rounds. Hard armor plates are available from many manufacturers, in both metal and ceramic.
Metal Armor Plates
Metal plates are the original form of modern body armor, and trace their lineage back to the Middle Ages. Metal was long the only option for those who needed protection from high-velocity and armor-piercing rounds. Metal hard armor plates are strong, durable and widely available, but that does not mean they are without their drawbacks.
Judo (meaning "gentle way") is a modern martial art, combat and Olympic sport created in Japan in 1882 by Jigoro Kano . Its most prominent feature is its competitive element, where the objective is to either throw or takedown an opponent to the ground, immobilize or otherwise subdue an opponent with a pin, or force an opponent to submit with a joint lock or a choke. Strikes and thrusts by hands and feet as well as weapons defenses are a part of judo, but only in pre-arranged forms (kata,) and are not allowed in judo competition or free practice. A judo practitioner is called a judoka.
