Generation Kill is a seven part miniseries that premiered on HBO in the summer of 2008. It is based on the book of the same name by Rolling Stone writer Evan Wright, who was embedded with the Marines of the First Reconnaissance Battalion during the initial stages of the 2003 US invasion of Iraq.
The following weapons are featured in the miniseries Generation Kill:
Rifles
M4A1 Carbine
The M4A1 Carbine is the main rifle used by the Marines of First Recon in the miniseries, including Corporal Josh Ray Person (James Ransone) and Sergeant Brad 'Iceman' Colbert (Alexander Skarsgard). The M4s seen in the series all have full quad rails, and some have attachments like PEQ laser modules and various optics. Those without M203 launchers mostly have Knights Armament Vertical Grips on the forward rails. Sgt. Colbert's M4, which is the most unique of the M4 Carbines in the series, sports an AN/PVS-17 night sight (sometimes replaced with an ACOG scope), a M203 grenade launcher, rail covers, PEQ infrared laser modules, and an ERGO grip.
M16A2 Rifle
The M16A2 is carried by numerous Marines, including Lieutenant Nathaniel Fick (Stark Sands),
Captain Bryan Patterson (Michael Kelly), and Hospital Corpsman Second Class Robert Timothy 'Doc' Bryan (Jonah Lotan). The M16A2 has been mostly phased out for the newer M16A4, but because the mini-series depicts the Invasion of Iraq in 2003, the M16A2 was the standard rifle of most Marine units at the time.
Kalashnikov variants
Kalashnikov rifles are used by Iraqi soldiers, civilians and even American Marines, in particular one platoon commander, Captain Dave 'Captain America' McGraw (Eric Nenninger).
M40A1 sniper rifle
The M40A1 sniper rifle is used by Scout Sniper Sgt. Larry Shawn "Pappy" Patrick (Josh Barrett) to eliminate an enemy RPG team in episode 2.
Machine Guns
M249 SAW Paratrooper
Some of the Marines, notably Lance Corporal Trombley (Billy Lush), carry the paratrooper variant of the M249 SAW throughout the series. The M249 is also seen mounted on Marine UH-1 helicopters.
PKM
PKM machine guns are used by the Iraqi forces throughout the miniseries, sometimes mounted on tripods.
Heavy Weapons
Browning M2HB
Several Browning M2HB machine guns are mounted on the Marines' Humvees, and are often used in conjunction with the Mk. 19 grenade launchers to assault Iraqi positions.
M136 AT4
M136 AT4 anti-tank weapons are seen in the Humvees and then later at the First Recon encampment in Baghdad. None are seen used in the miniseries.
M203 grenade launcher
The M203 grenade launcher is usually carried by the Marine team leaders and officers, including Sergeant Brad Colbert and Lieutenant Nathaniel Fick. In episodes 5 and 6, the M203s are used to launch blue smoke grenades in an attempt to prevent accidental shootings at roadblocks. In one tragic scene, a smoke grenade is fired to only ricochet off the ground and strike the head of a civilian.
Mk 19 grenade launcher
The Mk 19 grenade launcher is seen mounted on several of the Marines' Humvees including Sergeant Colbert's. Seen operated by several Marines including Cpl. Anthony "Manimal" Jacks (Rich McDonald), Cpl. Walt Hasser (Pawel Szajda) and Cpl. Garza and is often used to demolish enemy strongpoints throughout the miniseries.
RPG-7
RPG-7 launchers are used by some Iraqi Feyadeen during their attempts to attack the invading American forces.
M242 Bushmaster chaingun
The 25mm M242 Bushmaster chaingun is the main gun of the Marines' LAV-25 armored personnel carriers. The LAV's are seen firing their Bushmasters after the First Recon encounters enemy forces at the bridge.
Handguns
Beretta 92FS
The Beretta 92FS pistol is carried primarily by Marine officers and NCO's throughout the miniseries.
Shotguns
Remington 870
Remington 870 shotguns are seen being carried by Meesh (Nabil Elouahabi), the Marine recon battalion's Iraqi translator, and Major Todd Eckloff (Benjamin Busch), the Battalion's executive officer.
Other
M18A1 Claymore
M18A1 Claymores are mounted on the barricades as part of the Marine roadblock at Al-Hayy in Episode 4.
Recoiless Rifles
After the recon Marines successfully capture a strategic bridge in Episode 5, the surrendering Syrian irregulars can be seen abandoning recoiless rifles and heavy mortars.
