Valkyrie is the modern telling of the plot to kill Hitler. The main character is decorated war hero and senior German army officer Colonel Claus von Stauffenberg (Tom Cruise). The plot to place a bomb underneath the table where Hitler is meeting his generals is a well known historical story. What is not often known is that it is estimated there were anything from 17 to 41 other plots against Hitler by his own military. Apparently more than a few Germans saw the evil that was their leader. On July 20th 1944 two 1kg charges of "Plastit W" were used in the bomb plot. Since only one charge was primed and detonated, Hitler survived again with perforated eardrum and underpants torn to pieces, while 4 others in the room died, including Col. Brandt (actor Tom Hollander), who shoved Stauffenberg's briefcase beside the table support thus unwittingly prolonged Hitlers life.
The following guns were used in the film Valkyrie:
Seen in many of the massing army sequences, in Berlin and in North Africa, the Karabiner 98k is the most commonly seen firearm in the film, and is (accurately) used by much of the German soldiers.
Walther PPK
Colonel Claus von Stauffenberg (Tom Cruise), as well as most of the German officers use Walther PPKs as their sidearms, most notably General Ludwig Beck (Terence Stamp) and Major Otto Ernst Remer (Thomas Kretschmann).
MP40
Many of the Wehrmacht soldiers are seen carrying MP40 submachine guns.
MG42
An MG42 is seen briefly when the Home Guard is mobilized during Operation Valkyrie. One is also carried by a D.A.K. (Afrika Korps) soldier in North Africa.
MG34
MG34s are seen briefly being used by the military guards surrounding the forests leading to "The Wolf's Lair" (Hitler's Prussian Field Bunker).
Luger P08
A Luger P08 is seen in the hands of a Wehrmacht officer, who fires it at Colonel Claus von Stauffenberg (Tom Cruise) and his men.
Walther P38
Surprising seen very little, Walther P38s are mostly in the hands of SS or Polizei officers.
This is Sergeant Kolbe, who in reality let himself bluff to open the gate for Stauffenberg against his orders.
Rheinmetall Fliegerabwehrkanone 38
FlaK 38 20mm cannons are used by the D.A.K. (Deutsches Afrika Korps) in North Africa to fire on British fighter planes. They are also used by the Home Guard Reserve troops to guard the streets of Berlin.
Kampfwagenkanone 30 L/55
A German Sonderkraftfahrzeug (SdKfz.) 222 armoured car is seen in one scene in Africa, with a turret-mounted KWK 30 L/55 20mm autocannon; the vehicle also mounts a coaxial MG34, not visible in this screenshot. Another is seen later in Berlin, also with the MG34 obscured in the screenshot.
