The Drakonit, manufactured by Elbit, allows the operation of a heavy machine gun on the roof of armored vehicles directly from the fighter's box without the soldier needing to extend their body outside and thus endanger themselves.Dual cameras for day and night are affixed to the outside of the Drakonit system, as well as a small radar that detects suspicious movements in the field and allows the force inside the APC to lock on and shoot at a target.The Achzarit is based on the Soviet-built T-54/T-55 tank, beginning with those captured from Arab armies during the Arab–Israeli wars. To make space for a troop compartment, the eight-and-a-half tonnes turret, the original superstructure of the chassis and the transversely mounted engine were removed. Non-Explosive Reactive Armour was installed over the original hull. The first model of the Achzarit entered in service in 1988.
