[@Frengo] Order 227 was executed only in july, Barbarossa started a month before that. I was actually going to include that but I figured it'd be really weird if we simply shifted the date forwads.

But yes the Russians shot their own men if they retreated. Russian morale was REALLY low during the first month, and everyone retreated constantly causing insane losses (even more so because of suicide charges). They used to have a team of 2 men roll up an old Maxim Machine Gun before a charge to 'support' the infantry. Then there were 1 political commisar and some submachine gunners as well, and if they noticed people were running back they'd shoot.

It gave Russians a choice: run towards Germans and try to shoot them and have an 80% chance of dying or run back to the MG and face a 100% chance of death. 

I'd pick the 20% chance of winning against the Germans, you know. :lol
