Something which is really really odd to watch - while not perfect footage of the more experienced Ukrainian territorial type troops and the likes (not regular army) they generally have OK situational awareness - don't run in each other's firing lines, lift/drop their weapon so as not to sweep friendlies, slightly better spread out (though could be improved), at least some degree of coordination under fire. Generally movement, awareness and reactions are a passable imitation both in style and effectiveness in actual combat of troops with a special forces background.
In comparison supposedly Russian regular army units, and supposedly more experienced units at that, show poor muzzle discipline, poor situational awareness, poor coordination under fire, etc. never mind those who have obviously been chucked into this situation with little more than a few weeks of haphazard basic training.
