Invaders from Mars (1986)
Invaders from Mars is the 1986 remake of the classic 1953 film of the same name. The film was directed by Tobe Hooper.
The following weapons were used in the film Invaders from Mars:
Chief Ward (Jimmy Hunt) and Officer Kenney (Kenneth Kimmins) carry Colt Python revolvers as their sidearms. They're seen holstered in several scenes, but only taken out when the two confront David and Linda in the school.
The US Marines, particularly General G. Climet Wilson (James Karen), Sergeant Major Rinaldi (Eric Pierpoint) and Captain Curtis (Christopher Allport), use M1911A1 sidearms. They're also held by the two Martian-controlled NASA technicians in Wilson's office.
The M60 is also one of the weapons carried by the Marines in the film.
A Browning M2HB is seen mounted on Marine jeeps.
M242 Bushmaster Chaingun
U.S. Marine Corps LAV-25s in the film are fitted with the M242 Bushmaster chaingun.
Trivia: The U.S. Marine Corps supported the production with equipment and Marine Reservists acting as extras. Thus, the LAV-25s in this movie are actual LAV-25s. Along with Heartbreak Ridge, another movie which received USMC support, Invaders from Mars is one of the first films to feature the LAV-25.
Mk 153 SMAW
An Mk 153 SMAW is used by a Marine to kill several Martians. The use of the SMAW in this film is notable, as the launcher had only just entered service with the U.S. Marine Corps in 1984, just two years before this film was released. This movie is likely the first-ever cinema appearance of the SMAW.
(Fake) M203 Grenade Launcher
Some of the Marines battling the Martians can be seen carrying M16 rifles fitted with M203 grenade launchers. These are the same fake M203 grenade launchers seen in various films made in the 1980s, such as Scarface, Heartbreak Ridge, Predator, etc.
The M72 LAW is seen carried by some of the Marines in the film.
