Continuity errors/Stargate

Stargate, the movie

• All Jack O'Neill's teammates are credited as "Lieutenant" in the ending credits. However, when you watch their visible military ranks on screen, it doesn't fit at all: Kawalsky carries Lieutenant Colonel insignas, yet he is called "Lieutenant" by O'Neill who should call him "Colonel" instead; Ferretti carries Technical Sergeant insignas, Brown is Senior Airman, Freeman is Staff Sergeant, and Porro and Reilly are Airmen First Class.
