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 Reconnaisance Battalion during the initial stages of the 2003 US invasion of Iraq.
The M4A1 Carbine is the main rifle used by the Marines of First Recon in the series, 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 had attachments like PEQ laser modules and and optics. Most are stock with iron sights. 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 relaced with an ACOG scope), a M203 grenade launcher, rail covers, PEQ infrared laser modules, and an ERGO grip.
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 is currently being 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 rifles are used by Iraqi soldiers, civilians and even American Marines, in particular one platoon commander, Captain Dave 'Captain America' McGraw (Eric Nenniger).
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.
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.
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.
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.
The 25mm M242 Bushmaster chaingun is the main gun of the Marines' LAV-25. The LAV's are seen firing their Bushmasters after the First Recon encounters enemy forces at the bridge.
A Remington 870 shotgun is carried by Meesh (Nabil Elouahabi), the Marine recon battalion's Iraqi translator, and Major Todd Eckloff (Benjamin Busch), the Battalion's executive officer.
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.
