Soldiers who did heroic deeds were executed for taking initiative? This is in the Stalingrad campaign. Now, I'm sure incidents like this happened, but the game portrays it as some common theme. This defies all military sense. The Red Army junior officers had a much more limited grasp of combat vs their counterparts, but this is frankly nonsense. A good Lt, even if you devalue his life in a Soviet way, is still a good Lt and effective battlefield commander, something the Red Army sorely lacked.
although the campaign is flawed, disobeying direct orders from a CO during wartime is definitely punishable by death.
Im not sure, but I think I remember the CO ordering the soldiers to leave the protagonist. And the soldiers went against that.
