How can you describe the wartime conditions experienced by those in World War I?

The wartime conditions during the First World War was worse.

Explanation:

The war fought in trenches on the front line. These trenches were long with narrow channels dug into the ground. The condition was very muddy, slimy, and uncomfortable. These conditions caused some soldiers to develop problems like trench foot and diseases. There was a continuous threat of shellfire. New weapons like poison gas and artillery killed many from afar. When soldiers were not fighting, they locked into a trench, which led many to become boredom.
