Probably Marine? Does it fly for any of the other services?
How about British ... they still fly them, and are sometimes in this country. I don't know about anybody else.
That's a Marine Air Station. They fix Harriers there. I am in Yuma often. The Marines are the greatest guys.
One Marine repairman is a woman, very intelligent, the daughter of two physicians.
No other US service flies them. The Brits the Spanish Navy and the Italian Navy also fly them, IIRC. The Brits have two versions, the GR.5/7/9 land based ground attack version (much like the USMC Harriers) and the Sea Harrier FA.2, which is more of an air-to-air fleet defense fighter.
