Why might the nazis be concerned about the survival of their military

Military power results in the creation of a strong country, which leads to stability, leading to a stable economy, which leads to obedient people, and a progressive group.

Also, as stated, healthy and well soldiers generally fight better, so the scientists were trying to find ways to solve environmental powers that would allow soldiers to fight in usually impossible conditions. With these inventions, the German army would be almost "unstoppable".

rephrase: "about an hour after dinner, i'd like to chat with my friend".

we made sure to put the future tense, and also making sure that we put commas and punctuation.
