!!For the 2012 video game:

* SugarWiki/AwesomeMusic: [[http://spacerecordings.bandcamp.com/track/survival]] This theme is what plays [[spoiler:When you get the Green ending]]
** Check out the [[http://www.youtube.com/watch?v=Xtt0ZezljHk trailer music]].
* HellIsThatNoise: Several. If you are in an area where there are thin men, there will be a high pitched growl. For fat men, a low continuous gurgle.
** Similarly, thin men and final boss make shrill, almost electronic, and disturbing screeches every time they are alerted to the player's presence (and attacking in the case of the latter).
* {{Tearjerker}} [[spoiler: The Green ending.]]

!!For the book:
* HarsherInHindsight: As if the terrifying descriptions of combat and death weren't bad enough, a man was killed at a screening of the film adaptation for refusing to stop texting.
* MagnumOpus: The film adaptation is Peter Berg's most critically successful film, along with ''Film/FridayNightLights''.
* ValuesDissonance: 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 [[StayInTheKitchen 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.
