Disengage
From Alpha Centauri Wiki
A unit disengages when the following conditions are met:
- it incurs 50% damage (relative to what it started the combat with)
- it is faster than its attacker (taking damage into account)
- it is not stacked with other units
- it did not attack on its last turn
- it is a combat unit
- Neither attacker nor defender is an air unit
- Attacker does not have the Comm Jammer ability
- it does not have the ‘Hold’ order, and is not in a bunker or airbase
- A valid retreat square is available, which is not a fungus square (unless the disengaging player controls The Pholus Mutagen) and is not adjacent to an enemy unit
