When first viewing the Australian Embassy in Tehran, you can see the flag flying in the breeze. Only problem is this flag is missing the 7 pointed Commonwealth Star under the Union Flag, there are only four stars in the Crux constellation and those stars are red with white borders each with only five points. This is the New Zealand flag.
They drive across the desert in a Land Rover right hand drive version. These were fitted with a gear shift lever and a manual clutch. When Keeter drives off he would not be able to engage gear with his broken left arm.
The F-117 is shown as a Navy plane and landing on an aircraft carrier. In fact the F-117 is an Air Force plane and is not designed to land on a carrier.
Harm says that he was 19 when he was in his third year at the Naval academy. The minimum age for joining the military and/or enrolling at a military academy is 18, Harm would have been only been in his second year at the age of 19. Cadets are required to do all four years too, there is no "skipping" a year in the academy, so a cadet that enrolls at 18 doesn't graduate until they are 22.
When Brumby is in Mac's office her rank insignia on her shirt collar is uneven with the left insignia being higher than the right insignia. No Marine Major would ever wear their rank insignia uneven on the collar.
When Harm turns to leave the Admiral's office he does an about-face to the left, which is wrong. An about-face is always done to the right. Harm has done it correctly before.
