Ukrainian troops have been selling weapon systems to Donbass/Russia for a long time, probably since the start of the war in 2014. And this is obviously not allowed by the military leadership, but done by frontline units on their own. Sure the “actual price” is higher, but its not like they have a lot of buyers to choose from. And for the poorest country in Europe, thats a huge amount of money.

This was reported a week or so ago on donbass-insider I think. With the tweet from Castelnau, also of interest is that France apparently supplied cluster munitions to the AFU which, firstly, is illegal, and secondly, they claimed a few years back to have liquidated their stockpile… But that’s just a small oopsie.
