Every participating unit would need to rearm, except for those with the ENE* special ability, or they are penalized in their next combat. The penalty is a -1 to damage from all weapon attacks (not physical attacks) made by the unit, and the unit cannot use any weapon-based (or equipment with ammo-based) special abilities (AMS,IF,HT,FLK,AC,LRM,SRM,TOR,NARC,BOMB,MDS,MSL,INARC,RSD,C3RS or ART).
* Aerospace Fighters with ENE that do not pay to rearm cannot use their BOMB special ability, but do not have any of the other penalties for not rearming.
To be included in Alpha Strike errata.
