Staff Sgt. Parrish claimed that McLain's siblings ran him off the road in a "late-model Bronco." The actual SUV was a Chevrolet Blazer.
While the Staff Sergeant is telling Walker and Trivet about the first time he met Corporal McClain he tells them he was singing the Marines Anthuem in his skivies.... It's actually the Marines Hymn not Anthuem and there isn't a Marine of any rank, alive or dead that would make that mistake, let alone a Staff Sergeant of his status...
