Attack = (10 * Unit Rank) + Bonuses
Defense = 10 + Bonuses
And in combat:
Damage Dealt = Unit's Attack - (Enemy's Defense - Penalties)
Damage Received = (Enemy's Attack - Penalties) - Unit's Defense
The bonuses and penalties are the ones inherited by characters in the second and third command positions, as well as skills like Fortify, Muddle and Rumors.
Additionally, damage dealt is multiplied by 2 while damage received is divided by 2 when your unit is Strong versus the enemy unit, while damage dealt is divided by 2 and damage received is multiplied by 2 when your unit is Weak versus the enemy unit. Also, final damage seems to vary by + or - 1 unit most of the time. Size of the units attacking and defending has no impact, surprisingly.
