Principles of Operation
Stand-Alone vs. In-Conjunction Plates
Stand Alone (SA) - designed to stop ballistic threats using the plate alone. No vest is required for this plate, as all the energy and fragments are stopped in the plate.
In Conjunction (IC) - designed to stop the specified threat within the vest/plate matrix. Some fragments may penetrate the plate, but are of much reduced energy easily stopped by the ballistic vest worn underneath. These plates are lighter, more comfortable, and less bulky than stand alone plates.
Tested to NIJ level IV without a soft armor backing. Stand Alone 10" X 12".
