What was common among survivors of trench warfare?

Question

Quizplus · Accepted Answer

Many survivors of trench warfare experienced what was known as "shell shock" and felt lost and disconnected upon returning to civilian life. This was a common experience among soldiers who were exposed to the harsh conditions and extreme violence of trench warfare. None of the other options are applicable as survivors of trench warfare were not likely to sue the military for damages, be promoted to officer positions directly following the war, or volunteer in military hospitals. While some may have helped train the next group of soldiers, this was not a universal experience.
