In German uniform?
If so, then that implicates NATO.
I suspect it is mercs.
Plenty of mercs fighting in Ukraine, on both sides, and most of whom had prior military service.
I wouldn’t be surprised if many of these guys show up in their old uniforms and without bothering to remove rank and insignia.
Where can motivated Westerners sign up to go fight for Ukraine against the Russian invaders there? It’s time the Russians got some some payback!
Check Biden has a lot of money on it in his seedy little mind he thinks he’ll be able to say he took down Russia.
A fool and a idiot all in one bag.
