A shield for shielding structures, vehicles and personnel from a projectile and/or an explosive blast generally includes a substantially planar shield plate adapted for attachment to a structure to provide protection to the structure. The shield plate includes a chassis having an interior surface facing the structure and an opposite outer surface, and a ballistic liner disposed on the outer surface of the chassis such that the chassis is more proximal the structure than the ballistic liner. The ballistic liner has an exterior surface facing the exterior environment.
