In the Rules of War section of Battle Fleet Koronus, the rules for ground war say that a unit's Strength is equal to 10% of the number of soldiers in the unit. So a unit of 500 Imperial Guardsmen has a Unit Strength of 50.
My question is what about armor units? Ten percent of "the number of men" in the unit is a little ambiguous. Does it mean the number of crew or the number of individual tanks?
