In combat, can a 6 Might unit kill two 5 Might units that each have 2 damage already marked on them by assigning 3 damage to each (for a total of 5 damage on each unit)?

Ruling: Yes, you can assign 3 damage to each unit to kill both. When assigning damage, you only need to assign enough damage so that the total marked damage (including previously marked damage) equals or exceeds the unit's Might.

Nuances:

• The rule does not distinguish between damage being assigned and damage already marked on the unit
• You cannot assign more damage than would result in lethal damage to a unit before moving to the next unit
• Imperial Decree does not change the math for lethal damage assignment - the game cannot look ahead to delayed triggers when determining what counts as lethal damage
