While it is performing a move, a unit that has the Speeder X keyword can move over or end its movement on terrain equal to or less than height X. Additionally, when a unit on notched bases performs a move, it skips step 1 of notched base movement, rotating the unit leader’s base.A unit with the Speeder X keyword must perform a free compulsory move action at the start or end of its Perform Actions step.If a unit with the Speeder X keyword performs more than one non-compulsory move action during its activation, it may not claim asset tokens that activation. Additionally, a unit with the Speeder X keyword that has claimed an asset token can perform only one non-compulsory move action during its activation.A compulsory move is a free move action. To perform a compulsory move, the unit performs a full move at its maximum speed. If it cannot do so, or if a full move would cause any part of the unit leader’s base to be outside the battlefield, it can perform a partial move instead, ending its movement as far along the movement template as possible.
