Production of Ural-4320 trucks was launched in the late 1970s. The main tasks for this vehicle were to transport cargo, people and towing trailers on all types of roads. The 6×6 wheel arrangement provided good cross-country ability on difficult roads, while the robust design and powerful diesel engine allowed it to transport loads weighing up to 7 tons. Over time, the design of the truck was improved, and improved versions are still being produced today. The vehicle was used to create a line of specialized equipment for various tasks: vehicles with closed bodies, mobile radio stations, radars, Grad multiple rocket launchers, and others. Special versions with a fuel tank mounted on the chassis of the base vehicle are used to provide fuel to military units. One such version is the ATZ-5-43203, which is used by the transport units of the Armed Forces of Ukraine.
