This had a nice pace and a good setup, but… I did find the use of the words bile and tattoo a bit out of context for what you were describing. Also, he was a solider, so I’m not sure why he had to “supress the bile & horror” over dead bodies, unless the bodies were mutilated or some other in human thing was going on. Some more description of what he saw might have helped.
Also, the use of the ampersand, seemed to break the flow. caused by character count?

Most every issue you raised could be explained by “character count”. That’s part of why i find this format so interesting; it let’s the reader fill in a lot of the blanks.
(the ampersands were from a previous version which has since been fixed)
