I don't wish to get into a WW2 argument on this site as virtually everyone including myself is an absolute WW2 nerd but come on - the Soviet union suffered at estimated 9 million dead and 20 million wounded or sick from its combat forces. Despite all the flack the single player campaign got and to be fair it was not representative of the entire war there were occasions where entire Soviet brigades were thrown away simply to hold the Germans up. German losses may have reached 6 million but only when attacked on all sides and overwhelmed by the 200 odd divisions the Soviets had hanging around after the Germans destroyed the first 120
The OKW faction in this game is built on the concept of grizzled veterans from the Eastern front being switched West for the battle of the Bulge, With allied troops you have more of a point but units like the 7th Armoured fought from North Africa to Berlin and the US had the Big Red One who undertook both Italian and then the Normandy landings because of their veterancy
I'm fairly sure that the most aknowledged source is 1:1.3 casaulty ratio in favor of the germans, of course this also includes romanian and hungarian forces and what not, but they are still axis.
The OKW concept in this game is historically bogus , german quality of troops was best in 1941, worse in 42, then worse in 43 and worse in 44 and so on.
And what does exactly this throwing away of brigades mean?
