No indication of numbers.
Video is a mix factory and of old stock training footage (because of different weather), neither of which can be dated, and presumably some newer images somewhere with similar weather to Ukraine today.
No indication as to location.
Taken two weeks ago according to youtube. The tanks are new and are obviously modified from images of T90Ms seen just a few months ago.
Not to mention that the only time we see a tank or something firing at an actual target - it misses.
