Factual error: All of the soldiers in the movie are wearing the Battle Dress Uniform, but at the time the movie took place (around the same time as the first Iron Man) that uniform was already phased out and replaced with the Army Combat Uniform. Also, all of the soldiers had their name tags on the left side of the uniform, where the U.S. Army tag is supposed to go, instead of on the right side.

Factual error: General Ross and Blonsky are shown in their Class A uniforms, and both of them are missing their U.S. insignia on the collars. Also, General Ross is shown wearing the infantry cross rifles branch insignia on his collar, but he would not wear a branch insignia as a general officer. I could give Blonsky a pass since he's a British officer wearing an American dress uniform for reasons not explained onscreen, but Ross should have known much better as a general with decades of service.
