A system of armor plates is adapted for protection of a structure against projectiles B and S of two characteristic calibers D<SUB>B </SUB>and D<SUB>S</SUB>, D<SUB>B</SUB>>D<SUB>S</SUB>. The system compres a main armor plate and an auxiliary plate mounted in front of the main armor plate at a distance therefrom. The auxiliary plate comprises a plate made of ballistic material and perforated with through holes of characteristic diameter D, 1.2 D<SUB>B</SUB>>D>1.2 D<SUB>S</SUB>. At least one hard-material body of diameter D<SUB>H </SUB>is disposed in each of the holes, such that the auxiliary plate provides at least destabilization of impacting projectiles S capable of free passage through an unobstructed hole of diameter D.
