Lyla, who is dressed as an Army soldier, calls an Army Sergeant "Sir" which would never be done. An Army Sgt would not be likely to overlook the mistake.
A soldier at the Military Prison stated he was going to "The Head" (Aka the bathroom), however Army soldier, like the ones in this episode, refer to the bathroom as "The Latrine". "The Head" is a term used by personnel of the US Navy and Marine Corps.
