Battle: Los Angeles (also known as World Invasion: Battle Los Angeles) is a 2011 science fiction war film starring Aaron Eckhart as a Staff Sergeant who is part of a Marine task force assigned to rescue the remaining survivors left in the city of Los Angeles devastated from an alien invasion. The film was made with the cooperation with the Department of Defense and the United States Marine Corps, who supplied the production with authentic armor and aircraft. Also co-starring are Michelle Rodriguez, Bridget Moynahan, and Michael Peña.
The following weapons were used in the film Battle: Los Angeles:
Staff Sergeant Michael Nantz (Aaron Eckhart) is notably seen firing a Beretta 92FS (used as the substitute for the Military M9) pistol at the alien soldiers during the final battle. In a continuity error, he is seen first firing the handgun and then in the next scene he is actually seen drawing the handgun.
The Colt M4A1 carbine is one of the main weapons utilized by the U.S. Armed Forces in the film. The rifle is seen in the hands of members of the 2nd Battalion 5th Marines including Staff Sergeant Michael Nantz (Aaron Eckhart) and Second Lieutenant William Martinez (Ramon Rodriguez). USAF Technical Sergeant Elena Santos (Michelle Rodriguez) and members of the 40th Infantry Division (CA ARNG) are also seen with M4's. The Marines' M4A1 rifles appear to be fitted with ACOG scopes, RIS foregrips, Surefire Universal weaponlights, and most interestingly, AN/PEQ-15 laser designators; an improved, compact version of the AN/PEQ-2 system first employed in the early 2000's. In several scenes, bayonets are seen fixed on the M4's. The M4s are also all equipped with what appear to be Magpul Back Up Sights (MBUS) though these are never actually used.
The M16A4 rifle MWS (Modular Weapons System) with RAS Rail System is also carried by various Marines. Joe Rincon (Michael Peña) is seen using the M16A4 as well.
The M203 grenade launcher 40mm grenade launcher is seen used by U.S. Marines as well. The grenade launchers mounted on the M4A1 rifles appear to be shorter M203A1 models, while the ones seen on the M16A4's are the M203. Cpl. Lee Imlay (Will Rothhaar) is notably seen using his M203A1 to detonate an explosive during the final battle.
The mounted version of the M240 machine gun is visible on the ramp of the U.S.M.C. CH-46 Sea Knight carrying Nance's Marines. The M240 also are seen mounted on Marine LAV's as well as the UH-1N Huey helicopter sent to retrieve the Marines at the police station. Nantz is seen manning the M240 when the Marines commandeer an LAV. Also, the coaxial-mounted version M240C is utilized by M1A2 Abrams MBT.
The Browning M2HB heavy machine gun is seen mounted on various Marine Humvee's as well as in a machine gun nest at the Santa Monica Airport. Cpl. Kevin Harris (Ne-Yo) is seen using a humvee's M2 to fire at alien soldiers on an overpass.
Several Marines could be seen mounting a Browning M3 at the side of a UH-1N Huey helicopter at MCAS Camp Pendleton (in a continuity error, they are seen mounted the machine gun twice).
One of the Marines is seen carrying the M136 AT4 after acquiring it from the wreckage of the FOB. Technical Sergeant Elena Santos (Michelle Rodriguez) uses it in the battle to destroy an alien drone. The sound editing crew seems to the treat the AT4 as a guided weapon, judging by the squealing lock-on tone heard before firing, despite the fact that Santos was actually aiming at the drone's flight path rather than the drone itself.
