How do you tell from a photo if someone is "well behaved and disciplined" ?
Well with a VIDEO (and there are a lot of them) you see their actions in a range of settings over time and hear what is being said.
As for a photo. Um, not sure. Do YOU have an answer to that? It was your question.
So before I get the shaming dump on me again, as someone who is a defender of Ukrainian independence, was present (briefly) at Euromaidan before Christmas 2013 , sends money to relatives in Ukraine (in the free parts and in the Russian occupied), sends money to relief charities and to support the Ukrainian war effort in the hope that it kills Russian soldiers, and as a mother, let me tell you what I do here on Mumsnet. I can get my to a reasonable extent in Ukrainian and Russian and know some of the locations that feature in the news. I sometimes dip into Russian media and social media to see what it says is going on. There's a lot of propaganda, ultra-nationalist sounding off and, despite phones officially being banned for Russian troops, some interesting from the ground reports, photos and videos.
Early this morning I spent a couple of hours poking around with three questions in mind, seeing what was fairly easy to stumble upon to suggest some partial answers. One of my answers is that there are clearly different levels of behaviour and discipline on the Russian side. How it breaks down percentagewise and whether one switches from brutal rapist and murderer mode to calm professional soldier and back again is something I can't say.
One image I posted was a grab I made from a video that showed older soldiers who seemed coherent and well turned out showing off captured NATO munitions. I tend to not post more than one image and it was illustrative. I could have linked videos a range of videos but life is too short to feed everything in.
I follow Trent Telenko, Phillips OBrien et al already so the pastes of their output on here aren't anything new to me. I see if I can turn over a stone that hasn't had so much scrutiny.
