Characteristics

On dry and stiff surface the vehicle is capable to climb 60% steep uphill and downhill forward and by reversing. Uphill start is possible on this gradient by help of interlocks. The nominal fording depth is 0.8 m, but 1.2-metre depth is achievable with preparation. The angles of approach and departure are 35°. Maximum side slope is 30% and vertical step about 0.6 metres. The terrain capability is further enhanced by a front-mounted
