Let's resurrect an old thread. Tsarist Russia experimented with a large (60t) tricycle tank that they thought would be able to roll over German trenches to bring fire to the rear of the German lines. The tank was called both the Lebedenko tank or Tsar tank. Personnaly, I think Bsar would be more appropriate. The tank was cancelled when the Russians realized that it would be very susceptible to artillery fire and mop handles placed in the spokes.
CHIMO! Derek
