Factual error: When Kim Baker arrives in Afghanistan, most of the Marines are seen wearing Desert marpat (Marine Pattern), when in reality, that camouflage was not widely adopted until 2004 to 2005. In 2003, it was in the testing phases, Three Color Desert or DCU (sometimes called "Coffee-stained") would've been the primary camouflage pattern for both Marines and Army soldiers.
Factual error: The Marines in Afghanistan in 2003 are seen wearing MTVs (Modular Tactical Vest), when in reality they should be wearing IBAs (Interceptor Body Armor). The MTV was adopted by the Marines in 2006 to replace the IBA. Lance Corporal Coughlin (Evan Jonigkeit) is seen wearing an IBA but none of the other Marines are.
Kim Baker: I'm wondering if you can give me something... On background, just about the security situation here and the state of the war in general.
General Hollanek: Yeah, I can give you something... This war's like fucking a gorilla, you keep on going until the gorilla wants to stop.
Kim Baker: I think I can paraphrase that.
General Hollanek: Knock yourself out.
