Just before the American attack on the hill, the commanding officer is pointing out positions on a 3D clay model of the hill with his M4 bayonet. He lays his bayonet on the table and covers it with a paper map, then steps over to the radio man in conversation. He then steps back to the map table and the paper map has disappeared.

In the beginning of the movie when Harry Guardino is begging Gregory Peck to send him home because he has enough points, Guardino has a set of papers which he stuffs into the netting of his helmet. In subsequent shots, those papers disappear from inside his helmet.

All of the American officers are wearing their bright rank insignia and Infantry branch insignia. In reality, officers rarely wore these items in the front lines because they identified them as leaders who then became prime targets for enemy snipers.

Real American hand grenades had a narrow yellow band painted around the tapered upper section to quickly identify them as live fragmentation grenades. However, the grenades in the movie have no such bands, indicating that they are either inert training grenades or movie props.

King company had a number of Republic of Korea (ROK) soldiers mixed in with its American soldiers. For example in S.L.A. Marshall's book, "Pork Chop Hill" on page 150 he states, "The other two [grenades] fell about 25 yards behind Kuzmick, wounding three of his three Koreans." Korean soldiers are mentioned many other places in the book, which is the source for the movie.

No Koreans are depicted in the film.

Most of the weapons used by both sides do not eject any empty cartridge cases when they are fired.

After he dies (with his eyes open), Coleman blinks three times.

All the deuce-and-a-half (2.5-ton) trucks used to transport troops--and jeeps have shiny enamel paint jobs. Combat vehicles have flat, non-reflective paint. Light can be seen reflected on the wheels and many other parts of these vehicle, which would make them a perfect target for enemy fire.
