The present invention relates to a laser based system for protecting a platform against an armament equipped with an optical homing head element, that includes a command and control assembly equipped with an interface to a detection and acquisition system that detects and locates a threatening armament and receives from it a warning about the detection of said threatening armament combined with data relating to it; and a laser source operable by the command and control assembly in order to produce the required energy for jamming the optical head of the threatening armament; and wherein the system is characterized by that it includes in addition a sectarian array of a plurality of end units that are connected unto the laser source for selectively routing laser energy from the source to an end unit that was selected by the command and control assembly as the end unit that is best suited under prevailing conditions for pointing at the threatening armament and attacking it by emitting a laser beam in its direction.
