ASU-85 was redesigned rather than PT-76, it is no longer the main turrets firepower that is attached directly to the body of the tank, through which the overall height and weight reduction from the original car, special particularly suitable for the transport aircraft. ASU-85 self-propelled gun used fire and assist the infantry attack or defense, it can kill tanks, light armored vehicles. One of the remarkable advantages of this gun is relatively small but fast maneuverability in various terrain, including swampy areas, or with steep slopes, make sure to follow firepower aid? for the military wing, including advances in high-speed practice.
D70 85mm caliber main gun, a maximum range of 10km, is derived from D-48 anti-tank guns can fire anti-tank ammunition, high explosive projectile thrown pieces with the number 45 members. In addition, the vehicle is equipped with coaxial machine gun 7.62 mm PKT SGMT or with the 2,000 members of bullets. TShK-2-79 viewfinder simultaneously control both the main battery and coaxial machine gun.
