Bayraktar
Other countries apart from Turkey, with TB2s would appear to include (in alphabetical order)

• Azerbaijan : Azerbaijani Ministery of Defence and Turkish Air Force
• Burkina Faso (Update : 07/01/2022)
• Equatorial Guinea
• Gambia
• Kyrgyzstan
• Libya
• Morocco : CN-AOM, CN-AOS
• Somalia (tentative)
• Ukrain

And odd ones

• TUAF304
• TUAF407
• and recently RSB7612 from Doha

While I do not doubt there's TB2s in Ukraine -- we saw them being tested at Keşan -- they are flown there, they do not fly there themselves, obviously.

@ 15:50 UTC : A visibly angry 001071 scratching the Turkish skies. Now it's being reported as having taken off from Mykolaiv. I'd be miffed too. And 200 knots ? A bit rich.
