Does a unit with Assault gain its bonus might when attacking into an empty battlefield if the opponent plays a damage action to kill it before the conquer?

Ruling: When a unit moves into an empty battlefield, it is a showdown but not combat, so there is no attacker designation and the unit does not gain the Assault might increase.

Nuances:

• Showdowns (moving into empty battlefields) do not trigger combat-related abilities like Assault
• Without the Assault bonus, the unit can be killed by damage effects that would not kill it if it had the bonus
