Do units heal damage after a showdown ends, including units that weren't in the showdown (at base or other battlefields)?

Ruling: At the end of combat and at the end of turn, all units everywhere in play heal all damage on them at the same time, regardless of how that damage was assigned or where the units are located.

Nuances:

• Damage does not reduce a unit's might value; damage is tracked separately and a unit is destroyed when damage marked on it equals or exceeds its might
• The healing applies to all units across all battlefields and bases simultaneously, not just units that participated in the showdown
