This is a custom livery recreated for the A-10A/C (NOT the A-10C II) based on the GI Joe "Tiger Force" Tiger Rat CAS plane from 1988. I had one of these toys as a kid and I have never not loved the paint job they put on a captured and repurposed Cobra Rattler. Your pilot has a matching helmet and matching drop tanks.
All credit for the creation of this killer livery go to Fish and Aqil over at the DCS: Livery Art Group. I think they did amazing work.
Photo credits go to Polo "The French guy without M 2000C".
