Abstract
A door breach training system comprising a first restraint assembly connecting a door to a frame. The door is attached to a lock jamb of the frame with a first restraint assembly that exposes a shear joint to impact from a projectile, such as shotgun round. Another embodiment further comprises attachment of the door to the hinge jamb with at least one second restraint assembly that functionally simulates a typical door hinge and exposes a shear joint to impact from a ballistic round. The preferred embodiment includes replaceable lock panels and hinge panels that are designed to break in a known manner in order to replicate those same failure modes for both door locks and door hinges in typical residential and commercial construction environments.
