What was the average survival time of a soldier in world war 2? What about officers?

Just had a friend tell me that his grandfather still has his officer papers from world war 2. He said that on the papers the average survival time of an officer in a battle was about 1:30 seconds. I was wondering if there was some truth to this and if so then what would be the average survival time of a soldier in battle.|||it's completely false. And there is not mean survival time in battle, only survival time per front. Getting an average survival time of a soldier in battle is impossible because it would involve standing on a battlefield taking controls, and the fact that one solder may live throght the entire battle, and another may die in the first 10min. On top of which, most major battles in world war 2 lasted several years, not hours or minutes.|||Well, it depends on where you fought. In taking the pacific islands, the marines suffered horiible casualties. However as far as survival in battle if an average could be identified, then it would be a lot longer as even in the most heated battles, that often lasted for days on end, way more than half survived. The question is very vague. In Iraq or afghanistan the average survival time would be very high, as less than ten percent of an infantry unit usually dies, and they are involved in several battles usually. There are way too many variables. What kind of battle. What is the size of the opposing force, their equipment. do they have heavy artillery'? Where are you at? if you are in the desert, and they have helicopters the survival time would be very short. Be more specific.|||Well during the battle of Stalingrad the average life of a rifleman was a week
