To elaborate further on my question, for each of the players in WWII (looking at the British, American, Russian, and German armies.) Was there a particular point where if a fighting soldier had survived in the war, there was a high probability the experience they had gained would see them through to the end?
e.g. If an American G.I. lived for 16 months, they had a ~80-90% chance of survival.
I know that such accurate and precise data may not be available but I wanted to know if such a thing was calculated.
Thanks
For Germans and Russians there was no such point excluding such exceptions. If you belonged to the airforce or navy you were likely to survive if you achieved a certain rank since you stopped combat missions all together. If you were a special propaganda figure you maybe were forbidden to take part in further combat operations but this was rare, some German Aces come to mind. For the army this was comparable but you still had a good chance of dying even if you had a higher rank. Iam not 100% certain for the Red Army but the Wehrmacht did not phase out soldiers if they served long enough. For the general soldier you fought until you surrendered or you were incapable of fighting. The closest to such milestone was being crippled or preferably being wounded so hard that the convalescence was very long and you didn't get send back to front.
From the German POV.
Experience was pretty meaningless for army soldiers, your destiny was mostly decided by beeing part of a unit which stood its ground and was grinded up or if you belonged to a unit which was bypassed in the major fighting and surrendered at bulk. Experience does not help a lot against artillery, and even if you survive due to your experience somehow that doesn't help since you are on the losing side and keep fighting. The only thing that matters is if you are lucky enough to be in a group which surrenders or in a group which takes the brunt of some attack. To make myself clear your chance of survival depended more on where you fought than how you fought. Even if you were "experienced" you just kept fighting if you survived anyways. It should be noted that experience obviously had some impact on survival but was a rather small factor. In Normandy units reported that green troops had higher casualty rates just by making mistakes in regards to enemy arttilery and mines ( The guns at last light: rick atkinson ). But overall it was more about luck.
The only exception to this are pilots. If you were experienced your chance of survival increased significantly. Some time ago i researched into this found that successful eastern front pilots were far more likely to score further victories on the western front and survive until the war than green pilots. This seems obvious but a lot of the high scoring people survived the war or had accidents and were not killed in combat. For the 200 highest scoring aces there was a clear correlation between survival and skill/experience. So at least for pilots there is a certain point were your experience allows you to have a significantly higher chance of survival than your green fellow pilots.
