Otherwise, all the rules are the same. The player rolling highest can choose who goes first. The person to the starting player's left goes next, and so forth around the group. Tanks can move 2 Move Units. Heavy Tanks can move 1 Move Unit.
All tanks can change direction whenever they want to.
If a tank attempts to move up a hill, the tank can only move half as far as normal. The range for combat is one Unit for regular Tanks and two Units for Heavy Tanks. Any target farther away than that may not be shot by that tank. If you are a Royal Ruritannian Player, you will want the dice to come up odd. Heavy Tanks cannot move and fire in the same turn.
