Battle of the Bulge is the 1965 World War II film that focuses on the events of the famous battle that occurred during the German winter offensive of 1944. As was customary for World War II films of the time, this film features an all-star cast including Henry Fonda, Telly Savalas, Charles Bronson, and Robert Shaw.
The production was filmed in Spain, which provided a large amount of armor and weaponry (sometimes anachronistic). Despite the several impressive tank battle sequences, the film has an end title that states many of the events and characters in the film were heavily "synthesized" to capture the "essence" of the battle.
The following weapons were used in the film Battle of the Bulge:
The M1 Carbine is seen briefly held by a German infiltrator disguised as a US soldier. M1 Carbines are also carried by US troops as well. The majority of these carbines are of the anachronistic Korean War era.
A Sten Mk II can briefly be seen being carried by an American soldier.
MAT-49
What appear to be MAT-49 submachine guns are carried by US troops guarding artillery at the rail yard. These particular SMG's weren't introduced until after the war.
MP40
The MP40 is used by German forces as well as by Lt. Weaver (James MacArthur).
Machine Guns
Browning M2HB
The Browning M2HB can be seen mounted atop American M24 Chafee tanks and American half-tracks. These half-tracks are also depicted as German vehicles.
Browning M1919A4 Machine Gun
Browning M1919A4 are seen mounted on the American M24 Chaffee tanks and is fired handheld by Sgt. Guffy (Telly Savalas). US troops fighting against German armor also use M1919A4's.
MG42
An MG42 is used by German troops at the Malmedy Massacre.
Handguns
Colt M1911A1
What appear to be the Colt M1911A1 is seen in the holster of US officers and used by Lt. Weaver (James MacArthur). It is also possible that some of these are really Star Model B pistols, as the 1911 had troubles firing blanks in vintage films, and the movie was filmed in Spain, so it would be available.
Walther P38
A Walther P38 is seen carried by German tankers including Colonel Hessler (Robert Shaw).
Other
Instalaza M65 Rocket Launcher
Wolenski (Charles Bronson) uses an Instalaza M65 Rocket Launcher with a blast shield to damage a German Tiger Tank. The upgraded bazookas were provided by the Spanish Army, which supported several war films and television series made in Spain in the late 1960s.
Mk II Hand Grenades are carried by US troops. Kiley tosses one into the turret of a German tank.
Trivia
M47 Patton
The tanks used in the film to represent the German Tigers are in reality anachronistic US made M47 Pattons.
M24 Chaffee
The M24 Chaffee is the tank widely seen in the film as the primary tank of American forces. While the M24 was introduced into the war at around this time, the more prevalent tank used by the US during this battle was the M4 Sherman.
