I agree with you this just telegraphs to the Russians on what to look for. Why the do it is to buoy LGB’s massive disapproval numbers.
Oh, come on. You think the Russians would not know anyway?
I do agree this is very late in the game. Those Stingers should have been close to Ukraine’s’ border before the big wave of Russian troops went in. After all, we are told our intel knew about this invasion well in advance, no? (And the intel was correct.)
