Jarhead is the 2005 feature film adaptation of the autobiographical book of the same name written by Anthony Swofford, a former US Marine Scout Sniper who chronicled his experiences of training and service in the Marines during the time of the first Gulf War. The film was directed by Sam Mendes and written by William Broyles, Jr., who himself was a former US Marine who served in Vietnam and co-created the ABC Vietnam series China Beach. Jake Gyllenhaal stars in the film as Swofford and cast includes Peter Sarsgaard, Jamie Foxx, and Chris Cooper. Two DTV sequels would follow: 2014's Jarhead 2: Field of Fire and 2016's Jarhead 3: The Siege.
The following weapons were used in the film Jarhead (2005):
Anthony "Swoff" Swofford (Jake Gyllenhaal) uses two Remington M40A1 sniper rifles in the film, first using one with a camo finish stock to train to be a Scout Sniper in Basic Training, the second a desert camo painted model with a foam rubber sniper cheek pad. Swofford never gets to fire his rifle in combat so to make up for this, he fires his rifle into the air at the end of the film to celebrate the war's end.
M16A2
The M16A2 appears numerous times in the film as the standard weapon of the U.S. Marine Corps, most notably in a scene where Swofford snaps under stress and holds Fergus (Brian Geraghty) at gunpoint with one and forces him to recite the Rifleman's Creed, then gives the weapon to Fergus and demands for him to shoot him with it, which Fergus refuses to do. Corporal Alan Troy (Peter Sarsgaard) uses it to During the Scout/Sniper training, The Marines are also seen using M16A2s converted to fire paintballs in a dismal attempt to take out their instructor, Staff Sergeant Sykes (Jamie Foxx) - one of the Marines taking a paintball to the face in the process. In one scene (during the desert party), the marines all fire live rounds from their weapons. Troy fires his rifle on full-auto, a feat impossible with this rifle without obvious multiple trigger pulls, suggesting different variants may have been used for some scenes.
M16A1
When the Marines watch the infamous "Helicopter Scene" in Apocalypse Now, soldiers in the film are seen armed with M16A1 rifles with 30 round magazines.
M4A1
When Swofford is speaking his monologue at the end of the film, Master Sgt. Sykes (if you look closely on his plate carrier vest it shows an insignia with three stripes and three rockers) is seen serving in Iraq armed with a M4A1 carbine fitted with an ACOG scope and RIS foregrip. A soldier can be seen using one on Swofford's TV as well.
Barrett M82A1
When MSgt. Sykes is seen serving in Operation Iraqi Freedom, a Marine is seen running by with a Barrett M82A1 sniper rifle.
Norinco Type 56
When the Marines watch the infamous "helicopter scene" from Apocalypse Now, the Việt Cộng fighters on the screen are seen with Norinco Type 56 rifles.
Machine Guns
FN M249 SAW
The FN M249 SAW makes a few appearances in the film, most notably when the Marines are having a party to celebrate the end of the war, wherein it is one of the weapons being fired into the air. Fergus is the most notable of users to use it during this scene.
M60
When the Marines are watching the infamous "Helicopter Scene" from the film Apocalypse Now, a door mounted M60 machine gun is seen in use.
M60E3
The standard used version of the M60 machine gun at the time of Desert Storm, the M60E3, is seen several times in the film. Its first appearance is when the Marines are crawling through barbed wire in basic training, when a soldier is ordered to fire live rounds over their head. A trainee snaps and stands up and is killed by a shot to the head from the weapon. Aside from smaller appearances, the M60E3 is not seen much more until the end of the film, when several Marines are seen firing M60E3s into the air, including SSgt. Sykes.
M60D
An M60D is seen door mounted on a Huey helicopter while a Marine plays golf to pass time.
Browning M2HB
Browning M2HB heavy machine guns can be seen mounted on the Tank Commander's hatches of M1A1 Abrams tanks (in reality visually modified British-built Chieftain tanks). One is seen on a Humvee in the parade when the Marines return home, and again in news footage of Iraqi Freedom, this time fitted with a gun shield.
GE M134 Minigun
When the Marines watch the infamous "helicopter scene" from Apocalypse Now, one of the helicopters seen fitted with GE M134 Minigun, which a door gunner is seen firing.
Handguns
Beretta 92FS
The Beretta 92FS, standing in for the U.S. Military issued M9, appears several times in the film, seen mainly holstered in Officer's belts. This includes Lieutenant Colonel Kazinski (Chris Cooper) when he motivates the Marines when they first arrive, one is seen in SSgt. Sykes' holster, and Major Lincoln (Dennis Haysbert) keeps one in a shoulder holster. Among the weapons seen fired into the air at the end of the film, a 92FS is used by one of the Marines.
Other
Cobray CM203 Launcher
The Cobray 37mm Launcher appears in the film mounted on several Marines' M16A2 rifles, most notably Fergus and Troy's rifles. These faux-launchers take the place of the actual M203, although some genuine M203s are seen, sometimes they even switch between the two in continuity errors.
M203 Grenade Launcher
The M203 grenade launcher is seen mounted on Fergus and Troy's M16A2 rifles sometimes taking the place of the Cobray CM203 launchers used in other scenes.
GAU-8/A Avenger
At one point during Desert Storm, the protagonists are patrolling in the desert when an Air Force A-10A Thunderbolt II happens upon them, strafing them with its' General Electric GAU-8/A Avenger cannon, destroying a Humvee and wounding several Marines. This incident is based on a similar friendly fire mishap where an A-10A mistakenly attacked a British Army unit during the first Gulf War.
M18A1 Claymore
An M18A1 Claymore mine makes a rather humorous appearance in the film when Fergus asks Swofford which way the mine should be planted facing, obviously having failed to notice the words "FRONT TOWARD ENEMY" on the front of the mine, which Swofford sarcastically points out.
M67 Hand Grenade
During their time in the Saudi desert during Operation: Desert Shield, the Marines are shown practicing with M67 hand grenades.
M136 AT4
In the scene where the Marines are digging their sleeping holes at the border just before the start of Operation: Desert Storm, an M136 AT4 can briefly be seen among some of the Marines' gear.
Mk. 19 Grenade Launcher
At the start of Operation: Desert Storm, a Humvee can be seen with a Mk. 19 grenade launcher mounted on the roof.
