Hi... I have some ideas about the aircraft of an Erusian AF character(this guy FEAF Capt. Russel Harrison Formal Uniform
), I don't know if you will be interested in the livery designs.
The ideas I got now is
MiG-29 SMT(Product 9-18) with Slovak digital camo in 2nd Usean Continental War (AC04)
MiG-35 with the same digital camo for the Erusian AF Pilot School(before the story of AC7, since it's close to the 29 that he flew 14 years ago)
SU-27UBM with Ukrainian digital camo for the Pilot School(for exam combat with rookies)
JF-17 for the trainees in the Pilot School(Since FEAF used to fly MiG-21s and JF-17 seems to be a cheap but efficient evolution of 21s)
