The data from the war in Afghanistan paints a pretty good picture of capability versus perception. The vast majority of the responses to troops-in-contact came in the form of precision munitions from F-16s or F-15s. What the "troops" want is not a good variable in understanding what the best method of providing CAS is. Everyone wants the A-10, it's sexy. The reality on the ground is that even in a low threat environment such as Afghanistan the A-10 doesn't nearly do the job as good as an F-16 for a number of reasons which I won't get into in a public forum.
The Airforce vision of CAS is precision munitions from both manned and un-manned platforms that present very little risk to both the operators of the platform and the infrastructure that support them. It would be a significant de-evolution of our capability as a military to continue to operate the A-10 purley on nostalgia and public perception of its' capabilities. I don't expect the public at large to look at this situation with nuisance or data, but let's use common sense if anything. The reason why the Afghan Airforce is operating A-29s and armed C-208Bs has much more to do with cost and sustainability than it does to do with effectiveness. In fact you can find multiple articles of Afghan brass complaining about how what we are giving them isn't particularly well suited to the mission they are expected to sustain. A couple of tool boxes and spare PT6 parts will keep that fleet flying for a couple of years. I don't see them really providing a meaningful impact on the battlefield however.
Being close to the ground is the Army's mission and they do it really well. Adding a couple gunned turboprops won't change anything on the ground today or tomorrow. We are training and developing doctrine for a near-peer threat. We've been focused on COIN too long, and developing budgets and technology for yesterday's conflicts is exactly what set us back in the early days of the GWOT. So consider for a moment that the F-35, despite it's many setbacks and runaway budget might actually do the CAS mission quite well. I'll take the laser guided 500LB bomb over a spray of Hyrda rockets when some asshole starts throwing IDF my way. By the time we procure, field, and properly employ something like the A-29 it's basically going to be limited to a low threat environment scout attack role. Hey doesn't the Army do that??!!
So I told you what this soldier wants, and what the Airforce is doing. Hopefully that's good enough.
