As programmers we are well trained to find the source of a problem, not treating the symptoms. The source problem is a lack of fire support for troops. This does not require an airborne weapon platform, fire support can be delivered by cannon and rocket artillery. And coincidentally this area is lacking in the US armed forces.

The Paladin is based on a chassi from like the early 1960s and can only do three rounds per minute or one round per minute sustained up to 22km. In comparison the Panzerhaubitze 2000 that can fire 10-13 rounds a minute continuously up to 30km. The 2016 Russian 2S35 Koalitsiya-SV can do 16 rounds per minute up to 40km, even the older 2S19 "Msta-S" manages 6-8 rounds per minute up to 24km. Not to mention the modern wheeled based systems like the Archer or the CAESAR which would be ideal for rapid redeployment against threats in a low intensity conflict.

And then we have rocket artillery systems, here the USA actually have a modern piece that is good in low intensity warfare, the M142 HIMARS. But compared to the Russians the US basically doesn't have any long range rocket artillery systems available for fire support.

But if you insist on having a CAS platform then forget about the A-10. Ask the Russians if you can buy some SU-25 Frogfoots. It's the best CAS in the world.
