Character mistake: The Captain of the USS Fragasso comes onto the bridge. A Petty Officer says, "Officer on deck," and salutes while looking out the forward windscreen. He should have said, "Captain on the bridge" and not saluted.

Starring: Eric Roberts, Caroline Williams, Jessica Chancellor
Factual error: Lieutenant Commander Sharp addresses the crew of the USS King. At the end, he shouts "Semper Fi." Marines say "Semper Fi," not Navy personnel. "Hooyah!" would have been more appropriate. By the way, I don't think bright metal collar insignias are worn with the blue camo uniform. They use subdued rank insignia. But I am not sure.
