In fact the A-10 was originally designed to fight the Soviet Union in highly conflicted air space. That fact that it has not had to do so lately is a bit irrelevant. Yes while it is an older designed aircraft its avionics have been continuously updated just as say the B-52 (anyone seriously calling for them to be retired en masse?) or the F-15. If you do not like the A-10 that is fine but be honest and not drag it down to suit your argument. The F-35 is not a close support air craft and whoever in the Army that is calling for it to do so needs to be fired now. Likely just another seriously flawed Obama general that needs pushed out anyway.
