In the scene where Dennis Quaid is chasing the Vice President you can see Marines in uniform in the background. They are all wearing the Dress Blue Delta uniform which is the khaki shirt and blue trousers. However, the rank on their shoulders is blue and yellow which is only sewn on to the Dress Blue jacket. The rank should have been green and khaki. You would never put a blue and yellow rank on a khaki shirt, you would be out of uniform. I don't know how the makers of this movie could let this happen. I mean, it doesn't even look right!
