The communication components provide equipment for internal and external station-to-station communication. The M239
smoke grenade kit provides a self-screening smoke capability for armored vehicles for concealing maneuvers or vehicle
activities. The exhaust smoke generating system provides a self-screening smoke capability for vehicles with model
AVDS-1790-2DR engine from diesel fuel in the vehicle fuel tanks and is used for concealing maneuvers or vehicle troops.
