Thanks for your information, much appreciated. You HAVE been helpful. If detailed statistical info on the average age of the German combat soldier throughout the war existed, then I was very curious to know what it was. But if it doesn't actually exist, then you've answered my question anyway. Thanks!
But as a general idea, the picture I'm forming is that the teeth elements in '39-'41 had a rough age range that fell quite tightly in the early twenties, with an average age of about 22 as Sid says. After that the age range seems to have gone from about 17 or 18 to about 40 or 45. Depending on exactly where the weight of numbers actually fell, it looks like the average overall age '42-'45 would have been somewhere in the late twenties or even early thirties. Again it would be interesting to know how this was actually represented within the individual combat units, if some tended to be younger and others older, or if the age range was spread more or less evenly throughout. Gerhard's 13th and 2nd Divisions sound very young for '43 onwards.
But it points to a unique aspect of the German experience of WW2 (in Europe). The USSR, USA and Britain seem to have finished the war with the same basic recruitment procedures they began it with, in other words the ever-larger mobilisation of the same demographic (almost every able body in the USSR's case, and staying within the twenties for the Western Allies). But for Germany the social burden of the war changed drastically from '42 onwards, which I suppose was a necessary result of having started the war but not being able to finish it successfully. It's as if Germany was engaged upon a series of strictly military campaigns '39-'41, all carried out by a very young and highly professional army. It wasn't 'war' as such, though it was to Germany's enemies right from the start, as it had to be. Only when the final victory proved elusive did the war really begin for Germany. I wonder how much resentment, if any, those called up later on had for the 'proud and arrogant' young men who'd gotten them into all this. Conversely, I read once of the contempt some POWs from the Afrika Korps of the early days had for later groups of POWs who'd 'f*cked it all up' as they saw it. If Gerhard or anyone can shed some light on that, I'd be very interested.
Thanks again for your posts.
