Arotech has broadened its horizon from making batteries and chargers in 1990 to military training simulators, and aviation and vehicle armor. Subsidiary FAAC supplies simulators, related software, and training for the US military, and various government and private industry clients. MDT Protective Industries and MDT Armor produce lightweight armor and ballistic glass for vehicles, as well as aircraft armor kits under the Armour of America name. Arotech also makes lithium batteries and charging systems for military and homeland security markets via Electric Fuel Battery and Epsilor Electronic Industries. The US government (through its military branches) is Arotech's #1 customer, representing about 40% of sales.
