Several soldiers in the film were played by actual soldiers from Combat Outpost Keating.

In multiple scenes after characters urinate a "zipping" sound effect can be heard as they refasten their fly. In reality Army Combat Uniform pants have button flies, not zipper flies.

After the ending credit song starts, the pictures of the KIA soldiers are shown along with a clip of the actor that played every one of them in the movie. After the song ends, there are various clips and interviews with the real soldiers and some of the actors, including two clips from the TV show "An Unlikely Hero" with Ty Carter and some words from him at the very end.
