Abstract
A ballistic grille structure is combined in a stacked array with a similar grille structure to yield ballistic performance capability greater than the ballistic performance capability of the original grille structure. The grille structures may be of the type currently used in single, unscathed deployments with each grille structure a truncated version of the current structure such that a synergistic projectile defeating capability is realized by the stacked array of truncated grille structures.
