Accidentally reread this. It got described in terms of the vampires who show up in the last 13 pages or whatever, and I didn't even remember them until I got there again. But other parts of the book were sounding familiar.
Gordy used the idea of humans advancing faster than the aliens expect, and I think Harry Turtledove also. Plus, no doubt, unnumbered golden-age short stories.
The original observation here is that soldiers with advanced tech whose experience is with fighting people at a much lower tech level will be ill-prepared for combat with near-equals is a good one, though.
This also uses the "submission" idea that Footfall. used heavily. The idea of what different cultures and species consider "honorable" is highly speculative, but the least likely outcome is that they end up all agreeing, and it's an area that deeply affects war and peace.
