Arctic Armageddon : USS 598 Dallas

Having been in the military I tend to get a little critical over technical inaccuracies. This movie was one of the worst I've seen. On the submarine, haircuts, uniforms, rank structure, and submarine features were so far off to be laughable. The submarine's executive officer (XO) wore the rank of a first class petty officer a mid-level enlisted grade ... not an officer. The helmsman wore the rank of a seaman, but referred to as a petty officer. It was inferred that the submarine had to frequently surface to exchange air. Torpedoes were launched through what appeared to me the missile launch tubes. Decisions at the Pentagon were being called by the Secretary of Homeland Security rather than the Secretary of Defense. I could go on an on but I'd advise skipping this one unless viewing for the comic effect.
