Casualties of War is a 1989 Vietnam War drama starring Michael J. Fox as a young US Army private who decides to stand up to his commanding sergeant (Sean Penn) when he and other men in his unit kidnap a Vietnamese girl with intentions to commit rape. The film was directed by Brian De Palma and was based on an actual incident during the war.
The following weapons were used in the film Casualties of War:
The M16A1 rifle is standard issue amongst all of the soldiers seen in the film. In Eriksson's squad, the members cross utilize the different weapons from time to time, usually manning a weapon when another is reloading, or injured.
Fake Colt XM177 Commando
Sergeant Tony Meserve (Sean Penn) uses a fake XM177, built up from an Colt Sporter II Carbine. What makes it weird is the unusual flash hider/muzzle brake which is too long for an XM177, the wrong diameter and has holes on one side only (the left side).
Type 56/AK47
The Viet Cong guerrillas use both full stock and folding stock AK47s (which are most probably Type 56 rifles) however in the real war, despite the fact that the majority of AK rifles were Chinese Type 56s, there were some original Soviet AK47s given to the NVA who supplied them to the VC.
Machine Guns
M60
The M60 machine gun is seen primarily carried by Corporal Thomas E. Clark (Don Harvey) in the film. However, nearly all of the members of the patrol take turns carrying and using the weapon, especially during "Mad Minute" fights. Sergeant Meserve (Sean Penn) fires the M60 during the firefight on the bridge.
The standard sidearm at the time, the M1911A1 is carried by all NCOs and officers and used by some Enlisted men during certain circumstances. Both CPL Thomas E. Clark (Don Harvey) and PFC Eriksson (Michael J. Fox) are seen carrying and using the M1911A1 for protection.
Other
M79 grenade launcher
The M79 grenade launcher is carried by PFC Max Eriksson (Michael J. Fox). It is notoriously seen used to blow away an incoming grenade thrown at him, which in reality did happen to PFC Max Eriksson during the Vietnam War.
M26 Hand Grenade
An unseen perpetrator uses an M26 hand grenade to attempt to blow up PFC Max Eriksson in the Enlisted Men's Latrine.
M29 81mm Mortar
M29 Mortars are seen in the fire base in the background and are featured when the VC use captured ones for an attack.
M72A1 LAW Rocket
M72A1 LAW Rockets are seen slung on the backs of U.S. Soldiers during marches or massing scenes. Also seen being uncrated by VC who are sorting captured weapons.
Trivia Special
Base Camp Wolf
In the days before CGI, filmmakers had to build the massive sets and use actors (not CGI composites) to populate those sets. In this film, Base Camp Wolf is an impressive and massive Army encampment with many REAL UH-1D Huey Helicopters taking off and landing every few minutes.
Period Beer Cans
Kudos to the Art Designer/Prop Master for coming up with period Beer Cans. PFC Eriksson (Michael J. Fox) sits at a bar with a bunch of empty Budweiser cans. Despite being a wee bit too large for the beer cans of the day, they are the correct straight side, removable tab beer cans that existed in the 1960s.
