If only one side has units remaining before the Combat Damage Step, is the step skipped or do the remaining units assign damage with no targets?

Ruling: The Combat Damage Step is skipped if units remain on only one side. The step only occurs if both Attacking and Defending units remain at the location.

Nuances:

• The clarifying sub-rule stating "if neither Attacking Units nor Defending Units remain" only addresses the edge case where both sides have zero units, which is already covered by the parent rule requiring both sides to have units
• The clarifying sub-rule is unnecessary but was added to clarify how the rule works compared to a previous version
