Besides terrible acting and writing, the mistakes in this movie would takes weeks to list, so I'll try to generalize. Uniform mistakes are clearly the result of not having a competent military adviser and a serious lack of funding. There is not one location in the alleged Afghanistan that looks remotely like anything in Afghanistan. The MEDEVAC helicopters shown after the first ambush are Marine, but the pilots are Army, and the interiors of the helicopters are not the model shown flying. Civilian doctors (and others) in Afghanistan are issued very specific identification cards, so the Company Commander (who is much, much too old to be a Captain) could have easily verified their identity. Despite alleged former military experience, none of the Grandparents correctly handles a weapon. During the first ambush in the quarry,(and several other times) the U.S. Soldier on the truck is using an enemy weapon mounted on a model of truck that was never used in Afghanistan. All explosions are clearly propane and gas explosions with no attempt to replicate actual explosions. There are violations of military protocol and tactics that are too numerous to list. The bottom line is that this movie was a waste of money to make, and should be an embarrassment for anybody associated with this dreck. IMDb should allow a "0" rating for garbage like this.
