The Green Berets is the 1968 John Wayne war film that was one of the few movies made about the Vietnam War while the US was still involved in fighting it. Holding a somewhat dubious honor of being the only (somewhat) pro-Vietnam War movie of the era, Wayne's film received substantial support from the Department of Defense, who lent accurate equipment and weaponry for the production.
The following weapons were used in the film The Green Berets:
At the beginning of the film, when a group of civilians and reporters are being briefed about the capabilities of the U.S. Army Special Forces, a number of captured weapons are seen on a display board behind the MSG Muldoon (Aldo Ray) and SFC McGee (Raymond St. Jacques), they include:
MAT-49
The MAT-49 sub machine gun was used widely throughout (then) French Indo-China with a great deal of them being left behind after the French defeat at Dien Bien Phu. The weapon displayed here could be a locally manufactured copy which chambers the 7.62mm Tokarev round.
M1928 Thompson
Also seen on the board is an M1928A1 Thompson. The M1928 and A1 models could have their butt stock removed and were commonly used by the Viet Cong because of their availability from the times of the First Indochina War, Chinese Civil War, and Korean War.
This ubiquitous Russian PPSh-41 submachine gun is also seen on the captured weapons display but, like the SKS, above it could very well be a Chinese clone. Sgt. Muldoon (Aldo Ray) refers to the weapon as a "ChiCom K50 submachine gun". The ChiCom version normally was loaded with a "stick" magazine instead of the drum magazine seen here.
Mle 1892 Revolver
An Mle 1892 Revolver is seen mounted on the captured weapons display.
Pistols
Colt Woodsman "Assassin" Model
A Colt Woodsman with both a modified slide and barrel to thread a suppressor is used by Colonel Cai (Jack Soo).
Shotguns
Browning Over & Under Shotgun
The Airborne Colonel who shoots skeet with Col. Kirby (John Wayne) (and who was the real commander of the Airborne School at Fort Benning, Georgia where the film was shot) uses a Browning over-under shotgun.
Remington Model 1100
Col. Kirby uses a Remington Model 1100 semi-auto shotgun while shooting skeet with the Airborne Colonel.
Rifles
XM16E1
In the movie, Kirby's men carry XM16E1 rifles noted by the presence of a forward bolt assist, partial magazine fence, and early model three prong flash suppressor. In actuality, the U.S. Army Special Forces were one of the first units to actively field the M16 in combat.
Mattel M-16 Marauder Toy Gun
Later in the movie, Col. Kirby is seen dramatically smashing an M-16 against a tree. If you look carefully, the "weapon" is actually a Mattel M-16 Marauder, a plastic toy gun manufactured in the 1960s. Also, it would be near impossible for him to smash the aerospace-grade aluminum receivers by hand against a tree, which is what he would have done to really render the weapon unusable to the enemy. Like in most movies, this was done just to give viewers a "macho" impression on the screen. The Marauder is also briefly seen in the hands of Kirby after the watchtower is brought down by enemy fire.
M1 Carbine
The M1 Carbine is seen mainly in the hands of ARVN troopers, VC fighters, as well as numerous US military personnel. Reporter George Beckworth (David Janssen) also is briefly seen with the rifle.
M1 Garand
The M1 Garand is seen in the hands of ARVN troops, strike team members, and enemy fighters.
M14
Both American and VC forces are seen using the M14 rifle.
T26 Tanker Garand Rifle
During the evacuation of the A camp, a MIKE Force member is briefly seen carrying the Tanker model of the M1 Garand.
Mauser Gewehr 98 Rifle
A MIKE Force soldier is seen with a slung Gewehr 1898 rifle after the battle.
Mauser Karabiner 98k Rifle
NVA Regular soldiers are seen grabbing their Mauser K98k Rifles during the extraction. It should be noted that both the NVA and the Viet Cong used a considerable number of Mauser Kar98k rifles during the Vietnam War (many of which were provided by the Soviet Union) and the rifles (along with the Mosin Nagant) were used alongside the more prevalent AK-47 assault rifle and SKS carbine.
T-62 Civilian Defense Weapon
During the VC/NVA Assault on the basecamp, three VC killed on the wire appear to be armed with T-62 Civilian Defense Weapon rifles/carbines. Similar weapons were used in the 1967 Dean Martin film The Ambushers as well as in the television series Get Smart.
Machine Guns
M60 Machine Gun
M60 machine guns are seen manned by door gunners in Huey helicopters as well as carried by US troops entering their tour of duty at the end of the film. This is one of the first appearances of this machine gun in a motion picture and is not likely a prop weapon (the production was granted full cooperation with the US Department of Defense).
M60D Machine Gun
M60D machine guns are seen mounted as door guns on several US "Huey" helicopters.
M60C Machine Guns
Paired M60C machine guns, part of the M16 Weapons System (quad M60Cs and a pair of 7-shot rocket pods), are attached to a UH-1 "Huey" (probably a C or D model) gunship in the movie.
Browning M2 Aircraft
Seen mounted on tripods throughout the A Camp is this aircraft version of the venerable Browning M2, easily denoted by the full-length ventilated barrel shroud. The reason for using the M2 Aircraft version in the film was the ease of blank conversion compared to the M2 Heavy Barrel ground gun.
Browning M1919A4 Machine Gun
A Browning M1919A4 Machine Gun is also used in the defense of the A Camp.
Browning Automatic Rifle
A Browning Automatic Rifle is briefly seen in the hands of a VC fighter during the assault on the A Camp.
GE M134 Minigun
Seen in the interior of "Puff the Magic Dragon" (a nickname of the AC-47 "Spooky" gunship, a ground-attack variant of the venerable C-47 Skytrain transport aircraft) are a pair of devastating GAU-2B/As, the Air Force designation for a variant of the M134 minigun. The AC-47D carried three such guns after the replacement of the SUU-11/A gunpod (which used the original fixed-mount M134 under its Air Force designation, GAU-2/A) with the MXU-470/A gun module starting in January 1967.
This is also one of the first appearances of this weapon in a motion picture: it appears the production managed this by borrowing a real military AC-47D.
Other
M116 75mm Pack Howitzer
M30 4.2 inch Mortar
Sergeant Peterson (Jim Hutton) and crew are seen manning an M30 4.2 inch Mortar during the VC attack.
M79 Grenade Launcher
The M79 Grenade Launcher glimpsed briefly (though never actually fired) in the movie is one of the U.S.'s more reliable light support weapons. An M79 is also carried by MSG Muldoon (Aldo Ray).
M18A1 Claymore
This standard (and extremely devastating) M18A1 Claymore U.S. anti-personnel mine makes a brief appearance in the film. The mine is a modified training model. In the 1960s and 1970s, the training model Claymores were green plastic with a blue painted stripe on the front. The green plastic was the same as the live Claymore so it looks most like live ordnance. Only from the 1980s forward did they use ALL blue plastic training M18s. The remnants of the blue paint are faintly visible on this model, though it would be obvious that a movie production would never use any live ordnance to begin with.
