The tank’s driving wheels and standardized tracks from the same model were installed on some of the updated units. The renovated units “have successfully passed routine tests and proved their effectiveness,” says the plant’s CEO, Viktor Androshchuk: “I would like to emphasize that this allows installing standardized T-80 tracks on T-72, T-55 (54) tanks, and all types of special and engineering military hardware based on these vehicles in future orders."

BTS-4 is equipped with a hydraulic-driven crane manipulator with a capacity of up to 12 tonnes, electric welding equipment, traction and additional winches. This allows performing a wide range of scheduled maintenance works and intermediate overhaul of armored vehicles in field conditions. To clear the roads and equip army positions, the hauling unit has modern bulldozer equipment installed.

In terms of tactical and technical features, the restored unit is on par with Russian-made BREM-1 armored repair and recovery vehicles. At the same time, the upgrading works have turned out to be far less costly.
