Why it's such a rare thing for a producer to hire someone who's been in the military to keep things authentic looking, I don't know. It's such a simple thing to do to make sure your movie doesn't completely lose all credibility, but very few military themed movies take that necessary step... unfortunately. The guy is supposed to be a PFC during his deployment, but in the ceremony when he gets home he's wearing PV2 rank, which is a rank lower, but they're calling him a Specialist, which is a rank higher than PFC... totally confusing since anyone familiar with rank thinks the guy has been demoted for something at first. That's just one example of many. For a combat veteran, this movie was a total cringe fest the entire time.
