I was browsing the internet and I found this https://www.youtube.com/watch?v=1WO0zSStdj8
Apparently, it's a squad of Russian Soldiers refusing to go back to the front line. The fat guy says they were NOT getting food or water (yeah I heard it), I am pretty sure he is right. So, what are the types of conditions you have to face to get water and food at soldiers? I mean, I can understand them not getting ammo and man power to get rid of the dead. Probably manufacturing problems and it's dangerous respectively. But yeah, what else? Why would they not get food and water?
This is part of how a much smaller army can defeat a larger invading force. The locals have all their supplies. The invading force has to bring everything with them.
Home soil advantage, yeah love it! But don't you think for those soldiers in foxholes out in the middle of nowhere (ukranian or russian) supply would be not ideal?
