A ballistic door providing barrier-of-entry shielding blocks a doorway in certain emergency situations to shield against active shooters, while not inhibiting, impeding, or changing the safe egress through the ballistic door. A ballistic assembly may be secured to the non-threat side of an existing door, by retrofit installation or by new construction installation. The ballistic assembly has a ballistic skin, a top ballistic skin clamp, and a bottom ballistic skin clamp. The top and bottom ballistic skin clamps secure the ballistic skin against the non-threat side of the door. The ballistic door has at least a N.I.J. Level IIIA of protection against gunfire.
