The A-10 was a severe case of over-specialisation. It was desighned to kill Soviet tanks in WW3. Problem is, WW3 never happened.

While the old bird is still on the books, better and more effective alternatives exist. Experience has shown that the A-10 just isn't needed in her original role ad has been tasked in the Gulf and Afghanistan with operations better suited to COIN platforms.

I think half the reason the A-10 is still in service is because nobody is willing to accept that the West wasted so much money and resources in the cold war.

That being said, i doubt you'd find many spare GAUs in the twilight war. Mainly because this is the war the A-10 was built for and it would be one of the planes that gets first crack at repairs and resources to keep airworthy, especialy later in the war when air superiority birds are few and far between and SAMs become equaly rare.
