We Were Soldiers is a 2002 Vietnam War film based on the book We Were Soldiers Once...And Young by Lt. Gen. Hal Moore, US Army (ret.) and former UPI reporter Joe Galloway that chronicled the first major battle between the United States Army and the People's Army of Vietnam in the Ia Drang Valley in the Central Highlands of Vietnam. Gen. Moore, in the documentary seen on the DVD, states that this film is the only one which gets "[the Vietnam War] right." The film was directed by Randall Wallace (The Man in the Iron Mask) and stars Mel Gibson, Barry Pepper, and Sam Elliott.
The following weapons were used in the film We Were Soldiers:
The XM16E1 assault rifles are used by the soldiers of the 1st Battalion, 7th Cavalry Regiment, including Lieutenant Colonel Hal Moore (Mel Gibson), First Lieutenant Charlie Hastings (Robert Bagnell), Second Lieutenant Jack Geoghegan (Chris Klein), Sergeant Ernie Savage (Ryan Hurst) and most U.S. Army soldiers. Later on the film during the Battle of Landing Zone X-Ray, Joe Galloway (Barry Pepper) uses one as well. Many rifles used in this movie were not actual XM16E1s. The historical XM16E1s had only a partial magazine fence. Many rifles were actually M16A1s mocked up to look like XM16E1s, modified with chromed bolt carriers and 3 prong flash hiders. Apparently there were a few original receiver marked XM16E1s in the mix.
M16 Rifle
Supplementing the large number of XM16E1 rifles built for the production by Cinema Weaponry are some slab side M16 rifles (or unaltered Colt SP1 rifles, which look the same). To the left of the stack (in the screencap) is a slab sided rifle with no forward assist on the upper receiver or magazine fencing on the lower receiver.
M1 Carbine
A Korean War-era M1 Carbine is carried by the ARVN (Army of the Republic of Vietnam, the formal title of South Vietnam) interpreter dressed in tiger stripe fatigues. He appears in the scene in which the NVA scout is captured and interrogated. Viet Minh soldiers also use them against the French during the intro.
AK-47
In the film, the NVA (North Vietnamese Army) aka the PAVN (People's Army of Vietnam) used AK-47s with milled receivers. As per the actual battle, we also see several Viet Cong units carrying the same rifle. Real Soviet AK-47s were impossible to get in the U.S. for many years. After the fall of communism, milled receiver AK-47 parts kits were available on the market, and authentic AK-47s were built for the film (using American made milled receivers using the proper markings) and the original Soviet built parts. The AK-47s used in the movie were built by legendary Movie Armorer Mike Papac.
MAS-36 Rifle
In the opening scene where the French soldiers are ambushed during the French-Indochinese War, various French soldiers use MAS-36 rifles.
SKS Rifle
Several Viet Minh soldiers and NVA soldiers use SKS rifles during intro sequence and during the Battle of Ia Drang.
A Viet Minh soldier during the intro sequence and a Vietcong soldier later on can be seen using Karabiner 98k rifles. It should be noted that according to one of the Armorers of the film, Steve Karnes, the Kar98ks used in the movie came from Israel and were chambered to 7.62x51mm NATO.
Machine Guns
M60 Machine Gun
The M60 machine gun is used by several US soldiers. Various door gunners use them as well. Specialist 4 Russell Adams and his assistant gunner Specialist 4 Bill Beck also use an M60 in a deleted scene.
Browning M1919A4
Two Browning M1919A4s can be seen mounted on French jeeps on the intro sequence.
GE M134 Minigun
A pair of GE M134 Miniguns are seen mounted on the gunship Hueys that rip apart PAVN soldiers in the climax of the film, and one is also on display on a table near the beginning of the film.
Degtyaryov DP-28 Machine Gun
In the scene where the men of the 1st Cavalry Division perform a bayonet charge against the NVA position (an event which actually didn't happen in real life), a small crew of PAVN soldiers man a DP-28, a variant of the Soviet Degtyaryov light machine gun.
RPD Light Machine Gun
During the Battle of Ia Drang, one PAVN soldier can be seen carrying an RPD light machine gun.
ZB26 Light Machine Gun
A ZB26 Machine Gun is used by a Viet Minh machine gunner during the opening sequence of the film set during the Indochina War. According to Steve Karnes, the movie's Armorer, the ZB26 used in the movie was sold to the Chinese and converted to 7.62x39 later in its life. It also has Chinese characters on the side of the receiver.
MG34 Machine Gun
When the American Soldiers charge the NVA position, a two man crew of NVA soldiers man an MG34 machine gun before they get killed by the Huey helicopters. One NVA soldier also mans another MG34 in the same scene.
Fake DShK Heavy Machine Gun
A fake DShK heavy machine gun is seen manned by an NVA machine gun team in the final battle before being wasted by the Huey helicopters. The DShK seen in the film is actually an Browning M2HB machine gun mocked up to look like a DShK.
Handguns
M1911
A Colt M1911 is used by Command Sergeant Major Basil Plumley (Sam Elliott) as his main weapon since he prefers the .45 over the M-16; When Moore praises the latter, Plumley says, "Bah, it's plastic...feels like a bb gun to me. I think I'll stick with my pistol." It is not common to see the first model of the M1911 being used by Plumley, since the M1911 was replaced in 1924 by the improved M1911A1 which was the sidearm of the US Military in the Vietnam War, World War II and the Korean War, however they did appear on occasion, usually under special circumstances. Of note is that in real life, Plumley also carried an M14.
M1911A1
A Colt M1911A1 is seen in the holster of Lt. Col. Hal Moore and most of the soldiers of the 1st Cavalry Division that appear in the movie. Some soldiers use the M1911A1s.
Smith & Wesson Model 15 Snub
The .38 caliber revolver pulled out by Maj. Bruce "Snake Shit" Crandall (Greg Kinnear) is most likely a Smith & Wesson Model 15 snubnose. In 2007, the real Crandall was awarded the Medal of Honor for his actions at the Battle of Ia Drang Valley.
Browning Hi-Power Pistol
During the Intro of the Movie set during the Indochina War, a French Officer (Foreign Legionnaire) uses his sidearm, a Browning Hi-Power, to kill several Viet Minh soldiers before being killed himself. The use of the Browning Hi-Power pistol by the French Army in the movie is an error. The armorers couldn't get an appropriate French military pistol and since Hi-Powers were at the region, the armorers used those instead.
Submachine Guns
M1928A1 Thompson
As the American soldiers are heading off for battle you can see a ARVN soldier holding up an M1928A1 Thompson with a 20-round magazine.
PPSh-41
The NVA and the Vietcong use PPSh-41s submachine guns during the intro sequence and the rest of the movie, with both the standard drum magazine and 35-round box magazines.
PPS-43
The Viet Minh uses PPS-43 submachine guns along side their SKS's and PPSh-41s to kill the French soldiers in the intro sequence that takes place in 1954 in the Indochina War. During the rest of the movie, the PAVN (People's Army of Vietnam, the formal name of the PAVN. Also known as the North Vietnamese Army or NVA.) and Vietcong (Informal name for the National Liberation Front, or NLF.) use the PPS-43 sub machine guns against US Army soldiers in the Battle of Ia Drang.
MAT-49
Various French Soldiers use MAT-49 submachine guns during the opening Scene. Various NVA and VC soldiers use them during the rest of the movie, probably scavenged from French and South Vietnamese troops during the Indochina war.
Other
M26 Hand Grenades
In several scenes, U.S. soldiers can be seen with M26 hand grenades strapped to their pouches.
M79 Grenade Launcher
Various US soldiers can be seen carrying M79 grenade launchers in a few scenes. Specialist Galen Bungum (Blake Heron) uses one since he is the grenadier of Sergeant Savage's squad.
RPG-2
An NVA rocketeer is seen firing an RPG-2 (Vietnamese made version was known as the B-40) against the American forces. The soldier is wearing a protective hood and goggles worn to protect the shooter from the blast when firing the rocket.
M1A1 "Bazooka"
A Viet Minh soldier uses an M1A1 "Bazooka" with a modified rear sight to destroy a French jeep during the intro sequence. While it seems that a Viet Minh soldier using a Bazooka could be an anachronism, the French army widely used the M1A1, M9A1 "Bazookas" and M20 "Super Bazooka" during the Indochina War. The Viet Minh widely used scavenged French weapons during the Indochina War, and the PAVN and Vietcong also widely used them during the Vietnam War.
Hispano-Suiza HS.404
The M2 autocannon, the American license-built version of the Hispano-Suiza HS.404 appears in the film as the gun armament of US Air Force A-1H "Sandy" ground-attack planes that respond to the "broken arrow" call, making strafing runs on advancing Vietnamese infantry.
Colt Mk 12 Cannon
The Colt Mk 12 cannon can be seen in the film as the gun armament on a US Navy A-4 Skyhawk responding to the "broken arrow" call, strafing enemy infantry during low-level passes.
M34 White Phosphorous Grenade
A wounded NVA soldier is seen throwing an M34 White Phosphorous grenade (known during the war as "Willie Pete") at Sergeant Forrester, severely wounding him.
Chinese Type 67 Stick Grenade
Chinese Type 67 stick grenades (aka Chinese Type II Grenades) are seen in chest pouches on NVA soldiers and in one scene is thrown near wounded American Soldiers. A brave soldier jumps on it to save his comrades.
There are several errors also in the uniforms of French troops:
No lieutenant from "troupes de Marine" (2 golden horizontal stripes on bleu) would have a white kepi (Kepi blanc for Foreign Legion soldiers only, excluding NCOs and officers)
The red berets are worn the wrong way (Insignia on the right in France for all the Army. Only exception French Navy Commando green berets)
Insignia on the red berets are wrong (infantry instead of paratroopers)
Although the battle would last more than 300 days, the movie covers only the initial engagement, the first time the US used the Air Mobile Infantry (called "the helicopter soldiers" by a Vietnamese officer) in combat. Over 3 days, Moore's regiment suffered the loss of 72 out of his 395 men and were responsible for over 1800 enemy soldiers KIA out of 4,000. The utterly lop-sided casualty figures helped to convince Defense Secretary Robert McNamara and Vietnam theater commander Gen. William Westmoreland that the communist North Vietnamese could be persuaded to give up their attempt to conquer the South using attrition tactics. Events, of course, would prove this strategy disastrous.
