A Russian colleague in my previous research group is leaving this week - we just had coffee and cake to say bye to him, and he flies out to Turkey on Saturday. After that, he plans to return to Russia to visit his family for the first time in a while, and although he is unlikely to be conscripted, he said (somewhat casually) that "it's possible...". I don't envy him in any way, shape or form right now. I don't know how old he is, but I'd guess late 20's, possibly 30, very highly educated and physically fit.
It's a very scary thought to think that one day he's working at a top UK university doing world-leading research with people from all over the world - indeed, our little group of 6 that met for coffee just now represented 6 different nations (Scotland, Spain, Netherlands, Switzerland, China and Russia), and the next moment he could be faced with being called up to participate in a war, or face imprisonment if he were to refuse. I wish him well and hope that he gets back out of Russia as quickly as possible.
