Squirrel,
The USMC definitely wants and needs the F-35 as the Hornets are being used up quite rapidly. The discussion is best over some tequila (Scotch is reserved for calming enjoyable times so…).
USMC works around the globe in small detachments quite often, just less advertised than our counterparts in other services. The Harriers off gators attached to MEUs have been used at least a couple of times. Their use has not been denied just not noticed nor advertised. Another discussion best left face to face but with some Scotch (Talisker or Laguvalin) and a Camacho 11/18.
