Conversion
The BAD-2 had a set of special rail road wheels used on the railway. It takes about half an hour to replace all the wheels. After completion, the BAD-2 can be used as a light rail armored vehicle. Rubber tracks can also be installed on the rear wheels of the armored vehicle to transform into a half-track vehicle to enhance its off-road capability.
