I can understand why the USAF is trying (yet again) to get rid of the A-10 Thunderbolt II close support and ground attack aircraft. It's never particularly liked that mission, and wants to have all its jets to be high-speed, high-altitude, stealthy, sexy beasts. Nevertheless, the A-10 is beloved of the grunts on the ground, and can still put its ordnance on target with precision and deadly results.
Here's one of the more recent examples. What's described as an ISIL terrorist was riding a motorcycle when an A-10 caught up with him. WARNING: The slow-motion replay is fairly graphic. Don't watch it if you're squeamish.
I think that sort of attack is where the A-10 excels. I wouldn't like to see that capability lost.
