This film expression, the alien army and human technology power gap is not disparate, the U.S. military also took the opportunity to sunshine equipment, the current exposure of the stills in the audience can take a peek: weapons, combat vehicles, helicopters formations are complete, in addition to more than warriors ride - Humvee. Such as the Marine Corps warriors shoulder gun, staring indifferently into the distance, although just a glimpse, people still find that this gun is the famous M727 assault rifle, has a strong firepower and range, the furthest able to reach 600 meters, is the U.S. Army Special Forces one of the most classic equipment. A rare and deadly weapon in Black Hawk Down back in the day, it becomes almost a hand-me-down in Battle of Los Angeles. Although the Marines in the movie are made up of a group of unknown young actors, their professional and on-point performances are truly impressive and compare favorably to real Marines. Because the M727 has too much recoil and a relatively serious rifling noise, it is not suitable for female soldiers to use, for this reason, "The Battle of Los Angeles" to the heroic female soldiers with another classic equipment - M4 rifles, because of the outstanding performance in the Iraq War, by the U.S. Marine Corps and armored Mobility Brigade used in large quantities. The M4 has also proved to be the most suitable light weapon for single soldier use in the US Army's active equipment. All the actors of "The Battle of Los Angeles" underwent rigorous military training before the movie started shooting, and actress Michelle Rodriguez, who had an outstanding performance in "Avatar", was also highly evaluated by the military advisors - she was very reassuring holding an M4 rifle, performed every detail correctly, and, even if she was not reminded of it, was still able to perform the tactical maneuvers expected of a soldier in actual combat. One also finds two classic warplanes in the movie. The one that flashes by is most likely a Marine AV-8B Harrier, which is the most maneuverable and flexible aircraft for launching surprise attacks. Another set of shots in the footage shows a dozen helicopters breaking through enemy fire in search of human survivors, and this group is none other than the Apaches with their warheads removed. An armed helicopter battalion can destroy 84 light tanks, 8 guns and 38 wheeled armored vehicles in a single combat attack Apache, in the confrontation with the alien army, "out of food", the intensity of the battle if not to go to the cinema to experience it, just in the mind is very difficult to imagine. No wonder many military enthusiasts have been anxiously waiting for the movie since it was released: "Even if the old U.S. starts to preach individual heroism again, thinking that they are the only ones who can save the planet, the Battle of Los Angeles must be watched!
