Well, everyone have made reasonalble hypotesis (flat terrain)... but
- it is not Hungary, as it is covered by MAIW
- it is not Denmark because they have 30-years old Vipers
- it is not Greece
but Jetmax answered correctly!
This airport is Poznan-Krzesiny (EPKS) where two of the three Polish squadrons using the F-16 are based.
Looking at the plenty of photos available on the web, it looks like this airport has been completely refurbished with brand new buildings (control tower included) and shelters, leaving the old Soviet-style ones abandoned.
Please allow some artistic license: there were no suitable objects to depict the real shape of the control tower building...

... and the blast-deviating "pad" on the aprons (which is actually a burm covered by a concrete platform)

Also different is the main hangar: at the beginning I wanted to use one of the Atsugi buildings but its blue roof didn't look good in this kind of environment. If anybody has better solutions please let me know!
The scenery is almost complete though!
