The Land Ship, lacking anything like the control of a Steam Tank has two modes of movement: slow and full power. The player must declare which they are using before the Land Ship is moved each turn.
Slow: The Land Ship may move up to 6" directly forward without penalty or risk, but may not charge.
Full Power: The Land Ship follows the rules for Random Movement (3D6). However, if you roll two or more 1's when determining the Land Ships Random Movement, something has gone disastrously wrong. Roll immediately on the Land Ship Calamity Chart and apply the result.
