Plate Inserts for US Body Armor

When reading about modern body armor one often hears about small arms protective inserts (SAPI) or Enhanced SAPI (ESAPI) ceramic plate inserts. While these inserts are more fragile than past generations of inserts, they offer a significant improvement over its 1990s predecessors in terms of both weight and protection. After episodic issues with production ramp-up and quality control, this gear is widely fielded with the US Army and several allied militaries. The US Marines replaced it with the MTV. The Army itself has introduced the Improved OTV. Privately developed body armors like Blackwater Gear is also in theater. Yet all of these designs rely on a “vest and plates” approach that uses a similar set of inserts to give the vests most of their bullet-stopping power.
