Abstract: An armor designed for ballistic protection against armor piercing projectiles, comprises a main armor plate including a layer which is at least partially made of a ballistic material, e.g. in the form of a plurality of bodies, and an auxiliary armor plate at least partially made of a ballistic material. The auxiliary plate is located in front of the main armor plate and is spaced therefrom by an area, which is at least partially free of any additional layers. The auxiliary plate has through holes spaced from each other, which are free of any ballistic material.
