What happens when combat results in units from both players still being on the battlefield (e.g., due to stunned units not dealing damage)?

Ruling: If after damage has been assigned both players still have units alive at the battlefield, the attacker's units are recalled back to the base.

Nuances:

• There is a yellow gear (Symbol of the Solari) that changes this behavior, causing all units present at the battlefield to be recalled upon a tie.
