Logical. Perhaps a 'unit of strength'? Elves and humans would count as 3, halflings as 2 and a giant as 20?

Destroyers as 3, battlecruisers as 5, dreadnoughts as 10...

Exactly how you spread that strength around would be up to you. Your elves could be the 'west indian' type that are good with bows and like woodlands, or the magical type that live in shining towers, or the true olde faerie kind that live wherever they want and who's description includes such fun words as 'perilous', 'whimsical' and 'beyond human ken' (Extra point for disadvantage 'killed by scratch from iron')?

Missile destroyers, beam battleships, heavy armor/railgun battleships
