Might want to double-check your sources as from the information I've been given the location of whoever is posting that happens to be within Russian borders...
Which would make that a Russian captured weapon.
I do believe that ukrainians value these way more than to try to sell one.
Don't forget Ukrainian forces have killed over a thousand Russian tanks and need absolutely every one of these.
Russian forces, well they sell their own troops body armor. And the amount of corruption is systemic within the Russian forces.
Don't forget one of the Russian prisoners of War actually spoke of the fact that all of this valuable warfighting gear come up missing after it was issued to the troops. And of course then sold.
Also don't forget that Russian forces have been stealing absolutely everything and anything they could possibly get a hold of including toilets and shampoo.
And of course getting sucked into an urban battle at the bottom of a line of hills overlooking the Russian front. I mean we seriously need to have a conversation about the Russian leadership and whoever is allowing these crazy follies and all this military blunder.
Personally it just seems like there is way too many officers arguing bickering and tendering their opinions on what should go down.
And it really doesn't look like this is going to turn out very well in Russia's favor.
