North Yorkshire villagers at the beginning of the film use the ubiquitous double barreled Side by Side shotgun. A group of villagers use their side by side shotguns to kill the first werewolf.
Ingram MAC-11
During a nightmare sequence, David Kessler (David Naughton) dreams that a group of monsters who resemble werewolf like creatures dressed in distorted World War II German style uniforms massacre his family inside their home. (Trivia: the uniforms are not accurate for any group of the Third Reich, they are fantasy costumes). Two of the "Nazi" monsters carry Ingram MAC-11 submachine guns, chambered in .380 ACP, noted for their small side in the actor's hands. What is puzzling is that the rate of fire in the movie is about half the rate of a real MAC-11 (which is a very fast 1200 rounds per minute). The sound effect of the gunfire is about 450 rounds per minute (like an M3A1 "Grease Gun"), which is more probably due to the sound effect in editing, and not the actual rate of fire of the submachine gun.
IMI Uzi
In David's nightmare sequence. When the Nazi zombie werewolf monsters open fire with their Machine guns at Davids father as he opens the door. A weapon most likely an IMI Uzi sub machine gun can barely be seen on the left being fired
Sterling Mk.IV Submachine gun
In David's nightmare sequence, one of the "Nazi/Werewolf" attackers uses a Sterling Mk.IV Submachine gun (also known as the L2A3).
L1A1 Self Loading Rifle
The British L1A1 Rifle was seen being used by Metropolitan Police to deal with a rampaging werewolf. Contrary to popular myth that British police of the period were unarmed, there were actually many roving armed units of the Force Firearms Unit in the British equivalent of SWAT Vans that were ready to meet threats with military firepower.
