Czech AF's SU-25s

So much has been said of the withdrawal of MiG-21/23/29s & SU-22 from the former WARPAC air arms of Hungary, Poland, Czech.

But, esp for the Czech AF, how about the SU-25? The maintenance nightmare of the MiG-29 is well-known but does this apply to the FrogFoot?

Questions:
– Is the FrogFoot will still be retained in its inventory?
– Does this little attack jet’s maintenance better appreciated than the rest (of other Soviet-era jets)?
– So little has been said of this fine jet, but has the FrogFoot participated in any Red Flag exercises before?
– Is the Czech (or the other former WARPAC, but now-NATO AF) still retaining this jet?

Anyone?
