Not bad. Can't wait for more.

Did you really have to add the forced vegatarian diet onto the humans? It is such a cop out thing to do. In canon it is ambiguous is they are such, and in real life horse can eat meat just fine.

(I know Im late) Just letting you know, No one uses Sarge any more. I haven't heard it from active duty personnel since I've been in. We just shorten up the pronunciation into Sarnt. (pronounced Sar-int). Also NO ONE uses first names unless they're being an annoying ass. Or unless they knew you before enlistment but the odds of that are a million to one to be stationed together. Hell I've only ever seen ONE guy from back home get stationed at the same place as me but hes in a unit on the other side of post.

is there a story with this setup but more neutral or at least chaotic neutral on the moral alignment, humans should have some chaos to them
