When first questioned by Detectives Green and Briscoe, Sergeant Meacham's rank insignia on his beret is applied upside down.
Serena Southerlyn repeatedly mispronounces Ramstein as "Ram-steen." The proper pronunciation would be "Ram-stine." This is very odd, as actress Elisabeth Röhm is fluent in German, and holds dual U.S.-German citizenship.
Sgt. Meacham is an infantry soldier, yet doesn't wear the distinctive blue infantry shoulder cord, or the blue infantry discs behind the round branch insignia on his lapels.
