Anecdote: When I was 7 or 6 or something, I remember my granddad, who was in the Wehrmacht back then, very often explained to me how they fought during the war. One of the things which stuck with me was how many more people the Russians had in comparison with the Germans. He once drew on paper to explain how they did something like cross fire where they would just fire with the machine guns so the lines of fire would cross and from down the hill Russians would run up the hill, die on the way up and new Russians would come up the hill without weapons and would take the weapons of the dead Russians and keep on running until they died, then another ones would take their weapons and so on. I remember him saying it was 2000 Russian soldiers on one German soldier, but I guess that number got mangled through war propaganda, war reality, fear, and rumors on the front.
