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 not available, which is not a fungus square (unless Pholus Mutagen) and is not adjacent to an enemy unit.
