The system:• protects the tank by laying an aerosol

screen in the direction of the attacking enemy that employs semi-activelaser-guided anti-tank weaponsor laser rangefinders

• provides light and audio warning thatthe vehicle is being irradiated by a laser

• lays an aerosol screen automaticallyin the direction of the approachingenemy AT weapons

• enables the commander’s panoramicsight to be turned in the directionof the laser emitter

• masks the vehicle by laying an aerosol screen in the selected direction.
