Armor module

A reactive armor module for protecting a target from an incoming projectile, and comprising at least one armor cassette formed of a front base plate and a rear base plate sandwiching between them at least one layer of energetic material, the front base plate and the rear base plate being adapted, upon impact of the projectile with the energetic material, to be propelled in opposite directions; the armor module further comprising at least one non-energetic auxiliary plate spaced from the armor cassette and positioned essentially along the expected trajectory of either the front or the rear base plate, such that when propelled, the velocity of a base plate facing the auxiliary plate is reduced upon collision with the auxiliary plate.
