Zeus-23) is a fully integrated, self-propelled anti-aircraft system with four liquid-cooled 23 mm automatic cannons mounted on the front of a large, flat, armored turret. The chassis has many components borrowed from other Soviet armored vehicles, and the suspension system resembles that of the PT-76 and ASU-85 (six road wheels and no track support rollers). The driver sits in the left front part of the hull, and the rest of the crew (commander, gunner, and radar operator) are located in the turret. The GUN DISH (also a NATO designation) fire control radar mounted on the rear of the turret can be folded down during travel.
