In a showdown where my 2 units (total 12 might) fight an opponent's single unit (10 might), can the opponent kill one of my units even though their unit dies?

Ruling: Yes, the opponent can kill one of your units. Each player distributes their might as damage to the other player's units, then all units with damage greater than or equal to their might die simultaneously.

Sequence:

• Each player distributes their might as damage to opposing units
• All units with damage >= might die at the same moment
