The Air-force has been resisting the A-10 since it was first conceived and has been trying to kill it for decades
The reason for that was that the testing for the A-10 was cheated against the A-7 big time. The only thing they tested was the internal gun. The GAU-8 versus the M61; 30 mm versus 20mm. They didn't test much of anything else. Plus they didn't allow the A-7 to load it's own 2 30mm gun pods. The A-7E was almost 200 mph faster and carried almost the same load. It was also a mature weapons system.
The mission that Congress was fearing never came to play. The hordes of Armor (tanks) coming across the Varanda of Europe never happened. Had it happened, the A-10 would have had a field day because those tanks (t-54s and back) could not fire back and would be just mowed down. By the time it could have happened, the T-62 got the optics to shoot the A-10 but the horror of the enemas tank attack was past.
They ended up almost inventing a mission for the A-10. They took a mission that the AC-130 was perfect for and used the A-10 which the A-10 was vulnerable and the AC-130 was not. In fact, much of the film in Youtube is done by the AC, not the A-10 .
Meanwhile it has amassed an unsurpassed record in Air to Ground combat
And it was an AC without a mission so they invented one. Much like the Army did with their AH-64 when it first came out.
Airfields have been bombed ever since there have been airplanes
Ground crews have been able to rapidly put them back in service
