If you were a conscript born in 1920 and thus 19 and combat ready at the start of the war, your chance of survival was about 68%[1]. Interestingly, chances did not improve if you got conscripted at a later date. The reason for that is that losses started to rise with the invasion of the Soviet Union in June 1941 and again after D-Day in June 1944.

Fun fact: We would not know about this or indeed anything much about the German losses, had it not been for then US Army Lieutenant Henry Sternweiler and French Army captain Armand Klein. In June 1946 Sternweiler received, through his superior, an order from General Lucius Clay. Sternweiler to stop using the Wehrmacht archive to answer information requests from surviving families about the fate of the fallen. Instead, he should destroy the archive. Sternweiler approached Klein, who went to French General Pierre König. König had the archive transferred out of US and into French hands[2]. It survives to this day as the Deutsche Dienstelle.
