Of course, we all know the Marines are flush with cash and can build an entirely new infrastructure to support a new jet, set-up logistics and support necessary to service, maintain, upgrade, repair, arm and re-arm, and train many more pilots. And we can't forget the Marines will need to build runways (A-10s can operate from "austere" places but not dirt).
Nice to fantasize about but realistically, not feasible.
Uh, you do realize that the Marine Corps already has an air wing? As a matter of fact we have FOUR different Wings: three active duty and one reserve.
And surprising enough, those wings have the ability to repair and arm and re-arm them aero-plane, fly-ee thingy ma-gigs. Heck, we even got us some cement runways.
