These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Nightmare Fuel: The squad jumps off of a small cliff to escape the Taliban. When they're rolling down the hill below, there are lots of wince-inducing shots showing them landing in ways that could easily break bones or hitting obstacles very hard, and the whole ordeal leaves them significantly bloodier than the preceding gunfight.
Values Dissonance: Luttrel is a very conservative Christian from the American South, and has effectively no common ground with the also very conservative Muslim Pashtun. Still, he admires their courage and commitment to their idea of honor, and when describes the the Pashtun attitude towards women, and admits that while their extreme views "may not work for downtown Dallas," it seemed to work well enough for them.
