The mobility of motorized infantry does not meet the requirements of synergies with the tank forces, especially motorized infantry should not be in the area of ​​radioactive contamination or in the use of chemical and bacteriological weapons. To this end, the Soviet Union started to develop infantry fighting vehicles. Overall, at the time, the Russian industry was capable of developing infantry fighting vehicles, but the choice of infantry fighting vehicles became a problem.

Under such pressure, the first “victims” are anti-tank guns. Soviet army
