For the sleepingmoons I was thinking they should be equal parts gang and equal parts corporate giant. You do say that they are the wealthiest, let's delve into it, overseas drug trafficking, big time smuggling ops, either slave labor, or border hopping. Both are easy money and easy enough to hide with the right amount of money, also being the high end bastards they are would most likely carry concealable carbines, rifles, and shotties. While personal armaments could gravitate towards handguns, most would undoubtedly be fully automatic, with extended mags then that way they could still spray like with carbines and machine guns but with less accuracy and less stopping power. Now onto the legitimate side of the business, it would no doubt be something that makes quick bucks, hotels, casinos, no doubt they would have their hands in literally most any pie in the city at this point, at least in their territory. They no doubt would have mercs bolstering their people, easily affordable at this point but also easily scared off if they get too out of their depth. I'll have more later when I continue thinking this through.
