i sort stumbled on the troop thing in the race for space game, couldn't figure out why my morale was unaffected by losing a planet 5 ships and about 6 billion in pop in one attack, happiness stat was 50% by that time i had about 3,400+ troops throught the empire and only 120 planets didn't bring me up to 120 troops per planet by far but it added a nice cushion
