Obama’s appointee’s at the Marines and Army don’t want it either, it is just too effective and efficient ya know.
By law the Army isn't allowed to operate fixed wing combat aircraft; that dates back to the founding of the Air Force as a separate branch. As for the Marines, their combat aircraft and helicopters are all capable from operating from amphbious ships or aircraft carriers. Part of their mandate for amphibious operations. The A-10s can't do that.
