Tanks don’t have steering wheels, and their tracks don’t pivot like car wheels – yet they turn with surprising agility. The secret is differential steering: each track runs independently. Slow one side, the tank turns that way; brake one track completely and accelerate the other for a sharp turn; run both tracks in opposite directions and it spins on the spot. This same principle applies to all tracked vehicles – from bulldozers to snowmobiles. Watch the video to see how tracked chassis master turning in tight spaces.
