They were actually training on the eastern border of Ukraine yesterday. There are posts all over the internet about it. They aren’t expected in theater before the New Year.
Why do you ansk? You use be excited about them showing up?
IMO integrating Link-11 or especially Link-16 into the UKR command and control environment is a formidable obstacle. If/when UKR can do that they will essentially be a NATO-integrated military.
