After the invasion by Nazi Germany during World War II, the Soviet Union got a high demand in Ambulance vehicles and retrofitted their buses for these purposes. After the war, the problem changed and the country lacks in a vehicle for transporting people. So they began to re-equip the military ambulance vehicles into buses back. This recognition led to the post-war intention to create vehicles, especially trucks and buses that in case of war could be quickly and simply converted into vehicles for military purposes.
