A ballistic armor adapted to protect against armor piercing projectiles and to withstand multiple impacts of fragment simulating projectiles of a predetermined type, traveling at an initial velocity not exceeding a first velocity. The armor comprises a main armor layer and an auxiliary layer. The main armor layer is adapted to absorb most of the energy of the armor piercing projectiles and to withstand the impacts of the fragment simulating projectiles traveling at a velocity not exceeding a second velocity which is lower than said first velocity. The auxiliary layer is disposed in front of the main armor layer to face the projectiles, and is made of a material which is adapted to undergo a ductile failure mode when perforated by said fragment simulating projectiles and thereby experience localized deformation in the vicinity of each perforation, and which is adapted to cause the fragment simulating projectiles to experience such an energy loss associated with the perforation and deformation as to reduce their velocity from the initial velocity to a velocity not exceeding the second velocity.
