Corrected entry: Gunnery Sergeant Haney wears three chevrons and one "rocker", actually the insignia for the lower rank of Platoon Sergeant.
The Pacific (2010)
1 corrected entry in show generally
Starring: James Badge Dale, Jon Seda, Joseph Mazzello, Sebastian Bertoli
Factual error: The map shown has U.S. interstates displayed, but the U.S. interstate system wasn't developed until the 1950's. (00:06:30)
Correction: In the book "the Pacific", it's explained: everyone (including Captain Haldane and Cowboy) calls Haney "gunny" but he actually does not hold that rank. He was one of the few Marines to see combat in WW1, and was relegated to a stateside assignment in WW2, but he jumped a ship and headed for combat in the Pacific. Due to his experience, demeanor, etc., everyone respectfully refers to him as "Gunny" Haney.
