Well, unless it can give them a bunch of bionics or mutations the results of the rerolled stats/equipment are probably not going to be better than what I’m planning to give them all anyway right?
They are all getting MBR (ceramic) vests, military duffel bags, hard arm/leg guards, tactical gloves, and helmets, along with various clothing. At least 3 will be getting RM-13 combat armor. Plan to issue them a mix of Barrett .50 cal anti-material rifles and Browning HMGs, and a backup melee weapon (probably a mace or tazer). I’ve got shitloads of bionics too, if they will let me install them.
I probably won’t bother tinkering with their stats unless it really messes them up. I wasn’t exaggerating in the OP when I quoted the 40K Emperor of Mankind. I’ve stashed enough military grade weapons, armor, and bionics in the military bunker I claimed as my base to conquer several small countries.
