Military operation gone wrong

Hey everyone! As the title suggests, I'm looking for horror books that have a military operation gone horribly, terribly, and frighteningly wrong. Should be self explanatory, but soldiers should be the main unfortunate protagonists.

Here's some movies with the same vibes to help explain what I'm looking for:

"Predator" 1978 "Overlord" 2018 "Aliens" 1986

I know these are technically action movies but hopefully they help explain the vibe of a squad of soldiers facing something they're definitely unprepared for.
