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

Ukraine not only uses the same Turkish Mickey Mouse ADS-B addresses but the same callsigns too. Some coincidence, right ?
I'm fairly certain there are Turkish advisers there too.
