Disengage

Fast units, such as Speeders and Hovertanks, can sometimes disengage when surprised by slower enemy units. A unit disengages when the following conditions are met: * Unit incurs 50% damage, relative to what it started the combat with. * Unit is faster than its attacker, taking damage into account. * Unit is alone in its square. * Unit did not attack on its last turn. * Unit is a combat unit (non-combat units may never disengage). * Neither attacker nor defender is an air unit. * Attacker does not have the Comm Jammer ability. * Unit does not have the HOLD order, and is not in a bunker or airbase. * A valid retreat square is avaiable, which is not a fungus square (unless Pholus Mutagen) and is not adjacent to an enemy unit.
