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

The first problem is the problems Turkey and their pasha may find themselves in pushing their luck encroaching on the US's Syrian 'Green Zone' like that.

The other problem is that the tracker 'thinks' it took off in Ukraine while this is not a 001071 meaning a TB2 with 4B8378 as ADS-B address flew in Ukraine earlier today.
Why would the Ukrainians change the (assumed) default 001071 address to a legal Turkish ADS-B address and not a legal Ukrainian one or some Mickey Mouse address ?
Is it even more sinister ? Are there Turkish technicians in Ukraine to help the new licencee, who changed the address to a legal one already in use in Turkey ?

We and more specifically the trackers are in for more of this weird funky stuff now that Ukraine also produces/assembles and tests TB2s.
