The YouTube channel is a generally reputable source but this fact made me skeptical. When looking for confirmation of this fact the Britannica article on Stalingrad lists that the lifespan for a Soviet solider is 24 hours, whereas the video seems to depict a German solider as the host recites his opening line.
The thought that life could be so disposable during the Battle of Stalingrad is already difficult for me to come to terms with, and the slightly differing reports of which combatants had the shorter lifespan creates additional ambiguity. Other aspects such as "does this quote encompass the immediate area outside of Stalingrad" or "was this fact true for only specific operations during the battle" are unclear. An answer may reflect either a specific operation or the battle as a whole.
Did Soviet soldiers deployed to Stalingrad have an average lifespan of 24 hours? Did German soldiers have the same life expectancy too?
