After the legal BS/taxes/admin bs, Number one on my list would be a decent airworthy Gulfstream V and enough facilities/crew to run it. Then I'd go to the factory and order a G650ER. I'd also get a Pilatus PC12NG for the small dumb aiports/regional stuff. This would facilitate the use and acquisition of other real estate.
The gun thing is easy I'd deal with that later.
Multiple 07s and an ammunition wholesale business would be in the mix. It would involve lots of forklifts. I would also help TargetSports, Comm2a and others whacking dimples the tyrant....
