Factual error: In the original Transformers, Tyrese Gibson's character is credited as and wears the rank insignia of a USAF Technical Sergeant. In Revenge of the Fallen, set two years later, Gibson's character now wears the insignia of a USAF Chief Master Sergeant, three ranks higher than his rank in the first movie. The USAF would not jump someone three grades into the top 1% of the enlisted force no matter what his heroics or experience (that does not even happen to Medal of Honor awardees). Clearly the screenwriters recognized this as Captain Lennox is bumped only one grade to Major despite his actions in the first film and Gibson's character, as noted in another mistake, is credited as Master Sergeant Epps, a reasonable promotion. The costume department simply got the insignia wrong.

Factual error: During the credits, Tyrese Gibson's character is listed as USAF Master Sergeant Epps. However, throughout the whole movie, Gibson is seen wearing the sleeve chevrons of a CHIEF Master Sergeant. Chief Master Sergeant is the highest rank an enlisted person can hold and is NEVER referred to either verbally or in writing as Master Sergeant. Master Sergeant is a different (lower) rank.
