There are countless instances where Ukrainian A-10s would have raped Russian forces without challenge.
Aside from the fact that the A-10 can deliver precision standoff weapons, there have been situations such as Russian troops holed up in a block of flats that were barraged by FPV drones or an M2 Bradley.
Russian AFVs darting across open terrain without support, that were dodging FPV drones and artillery.
The list goes on, but as it stands, Russia has lost it's ability to operate with a well trained, supported and disciplined function.
