WiFi is a standard protocol. Russians are also clever with electronics. Gaining favor with the new guys is as easy as giving them an old phone. WiFi still works.

I don't think most people fighting for Russia are super indoctrinated on the Russian side; opportunistic, morally corrupt, maybe, but not super jaded. Even if you're fighting in dubious circumstances, the level of NK dystopian cult insanity is next level crazy. I can't picture anyone that is around those guys being totally passive about the extent of bowdlerization and disinformation present in NK. Like you've got a bigger humanitarian obligation to show those kids that they are living in The Hunger Games IRL.
