Your claims about those 13 - you provide no evidence, just sow baseless doubts. That's a russian playbook, saw them doing this and much more over past 20 years all around former warsaw pact countries to weaken them, with some success actually. From an account started 39 days ago...

Its obviously not a smart move to trust for example numbers of either side, that never worked in any conflict (unless you average them, but even then its just a guess).

As another user pointed out, there are videos of SAM vehicles passing villages near Kyiv, so it could have well been a russian one (but nobody here really knows). Anyway blame lies solely on invading russians for this one
