Self Destruction
From Alpha Centauri Wiki
Self-Destruction damage is dealt to all enemy units in surrounding squares (a 3 × 3 grid centered at the unit).
Self-Destruct damage = FLOOR[weapon × reactor class ÷ 2]
Damage is limited to 1/2 × reactor value
(i.e weapon >10 deal no additional damage)
Non-Combat modules have a weapon value of 1
Units within a base are immune to self-destruct damage
Armour of defender, current hit points of self-destructor have no effect
