Errores

On the train, Mueller says that God touched his heart and points at his heart in the side shot and there is a cut to Mueller and both his hands are on his cane.

Colonel Wilits is wearing silver jump wings with a star above it. Only the army wears this badge, the Marines wear basic silver jump wings if they have fewer than 10 jumps or no combat jumps. Otherwise, they have gold wings.

Col Wilits' rank insignia are positioned incorrectly on his shirt collar.

The uniform of the Air Force Security Forces airman is incorrect. The name "Miller" appears over his left breast pocket. The name tape goes over the right breast pocket and "U.S. Air Force" tape goes over the left breast pocket.

In the funeral scene, Lance Corporal Washington is wearing his Marine Dress Blue uniform but his cover is not square, it is cocked to the right. Marines are always "squared away" and that includes their cover.

In the funeral scene, Sal and Richard are wearing Marine Dress Blue uniforms but the cap ornament is set a bit high.

Incorrectly Regarded as Goof: Age of Steve Carell doesn't match up for Vietnam service. However, the movie takes place in the past. If you presume Steve Carrel is 55 (as he was at the time the film was shot) during the movie's setting of 2003, he would have turned 19 (when he was there as per the "Disneyland" story) in 1967, the height of the US involvement in the war.

In the captions the name "Marine" should ALWAYS be capitalized when referring to members of the USMC. The lower case "marine" is an adjective referring to the ocean as in "marine mammal."

While Sal and Muller are driving to and from the U-Haul store, they're supposed to be in central Delaware, near Dover Air Force Base, on the Delmarva Peninsula, which is one of the flattest places in the US. The highest point is less than 20 feet above sea level. In the film, they passed hills, houses on hills, and areas that looked much more like western Pennsylvania (shot in Pittsburg) than Delaware. Nothing worked, except for viewers who have never been in Delaware.

The proper way to verbally introduce a Lieutenant Colonel is with their full rank, and then shorten to the category of rank (Colonel) on subsequent direct addresses. Same for Generals, Lieutenants.

LTC Weber introduces himself as a Colonel. He should have used his full rank on first mention of it. This is unequivocally proper etiquette when first referring to yourself in written, in person, or on the phone communication.
