Corrected entry: The movie takes place in 1983, during the invasion of Grenada in October that year. The battle of Heartbreak Ridge occurred in Sept/Oct 1951. SGM ChooZoo informs Stitch that he, Highway and Stoney Jackson had left the Army after Heartbreak Ridge and joined the Marine Corp. At the time of the invasion of Grenada Highway would have had a total time in service of 32 years, 8 years past mandatory retirement for an E-7.
Corrected entry: As the recon platoon is heading toward their "ambush" of Major Powers and 1st platoon, Highway tells Jones to "unsling those rifles, and you're making too much noise." Jones starts to unthread his rifle sling from the buckle in order to remove the sling from his rifle. Anyone familiar with the manual of arms (which includes ANYONE who has ever graduated from USMC basic training) knows that to "unsling" a rifle means to take it off your shoulder (from a slung position) and carry it in your hands, ready to use.
Corrected entry: Gysgt. Highway has 6 service stripes on his uniform. Since each stripe is 4 years, that would indicate he's been in anywhere from 24 to 27 years (having not received his 7th one yet if this is the case). The movie takes place in 1983, yet he won the CMH for actions during Heartbreak Ridge in Korea in 1951, 32 years prior to the events of the movie. SgtMaj. Choozoo briefly states that their involvement in Heartbreak Ridge was before they joined the USMC ("We joined the Corps later") and that they were in the 23rd Infantry. The 23rd Infantry Division of the U.S. Army (as is implied) was involved heavily in WWII and Vietnam, but not in the Korean War, so this is historically wrong.
Corrected entry: Early in the film, Gunny Highway is tricked by Jones and is left stranded in the roadside diner when the bus they were on pulls away. Gunny Highway hitches a ride to the base and arrives with his two suitcases which would have been left on the bus while they were taking a short meal break.
Corrected entry: When the Recon unit lands in Grenada their rifles do not have slings on them. When they get to the fortress and scale the wall all their rifles suddenly have slings on them.
Corrected entry: When Highway beats up the Swede, Swede tells Highway "I'll wait outside for the M.P.s, sir". On a Marine base such as Camp Lejeune, the police authority would be the Shore Patrol(S.P.s) not the Army's Military Police, and anyone who's been in the brig as often as The Swede would know that.
Corrected entry: Gunny Highway is drunk in the other room while Mario Van Peeble is told how Highway won the "CMH" in the Korean War. He said their platoon sergeant, Stony Jackson, recommended Highway for the award. First, the award is called "The Medal of Honor." There's no "Congressional" in the title. Second, only officers can recommend soldiers for the Medal of Honor. Stony Jackson's rank was that of an NCO.
Corrected entry: Whenever a Marine Corps unit goes anywhere they are accompanied by a United States Navy Corpsman. So when Profile gets hit a "doc" should have been there to be responsible for medical care. Although Marines are trained in basic injury care, they are still accompanied by a Corpsman per unit.
