Die Hard is the 1988 action film starring Bruce Willis as John McClane, an NYPD detective who on Christmas Eve travels to Los Angeles to visit his estranged wife at the office tower where she works. He then finds himself having to battle terrorists who seize the tower and hold his wife and 30 others hostage. The film, which was directed by John McTiernan, spawned four sequels and helped launch Bruce Willis' action movie career. In addition, the basic plot of a single person taking on terrorists while trapped in a confined space would serve as the basis for a great number of action films in the following decades.
The following weapons were used in the film Die Hard:
The Beretta 92F features prominently in the film as the sidearm of Detective John McClane (Bruce Willis). At one point, Hans Gruber (Alan Rickman) is seen holding the Beretta. Karl (Alexander Godunov) gets ahold of it during a fight near the end of the film as well. Another Beretta can also be seen being carried by one of the SWAT officers involved in the ill-fated raid on the Nakatomi Building.
Heckler & Koch P7M13
Hans Gruber (Alan Rickman) carries a hard chrome Heckler & Koch P7M13 as his main weapon, notably using it to threaten Joseph Takagi (James Shigeta) and Harry Ellis (Hart Bochner), and then brandishing it at the climax of the film, holding McClane's wife Holly (Bonnie Bedelia) at gunpoint. When he first brings out the weapon while threatening Takagi, he is shown removing a matching suppressor from the barrel, thus indicating it's not a P7M13SD because there is no threaded barrel to use a suppressor. According to the script, Hans was supposed to carry a Walther (likely a PPK, but it's not specifically identified) It is assumed that the P7M13 was used in place of this, as it bears resemblance to a Walther PPK.
The terrorist Heinrich is seen pulling what appears to be a Walther P5 as he and Marco confront McClane in the boardroom.
During the takeover of the Nakatomi Building, Karl (Alexander Godunov) can be seen using a suppressed Walther PPK to kill the security guards at the front desk and by the elevators. He later has it without the silencer when he hears McClane leave following Takagi's death and goes to investigate.
Smith & Wesson Model 15
At the end of the film, McClane finally gets to meet Al Powell (Reginald VelJohnson) in person and is introducing him to his wife when Powell has to pull his Smith & Wesson Model 15. He is seen firing 5 rounds.
Heckler & Koch HK94 (chopped and converted)
Another frequently-seen weapon in the film is the Heckler & Koch HK94s chopped and converted to look like MP5A3s. The Heckler & Koch MP5 was often considered the Rolls Royce of submachine guns when it was first widely introduced to the market in the late 1970s/early 1980s, and are used primarily by Gruber's men (and occasionally Gruber himself). McClane manages to commandeer one from one of the terrorists, Tony Vreski (Andreas Wisniewski), informing his comrades of this by leaving a note on Tony's corpse saying "Now I have a machine gun. Ho Ho Ho.". At one point, McClane extends the stock hoping to use it as an anchor so he can descend down the ventilation shaft via the sling, though the sling doesn't support his weight for long, soon coming undone and sending him falling into the shaft before he catches himself on the opening of an air vent. He then procures another MP5 from another slain terrorist, using it until he runs out of ammunition during a gun battle with Karl. He then procures yet another MP5 from a terrorist on the roof, firing it into the air to scare the hostages brought up. He discards it when it runs out of ammunition before the final battle with Hans.
MGC M-16 Model Gun Corp Replica Rifle
When the SWAT team makes their ill-fated raid on the Nakatomi building, they can be seen carrying MGC M-16 Model Gun Corp Replica Rifles. Some M16's can be seen with 20-round magazines, while others appear to have 30-round magazines.
One of the most unusual weapons in the film, as the writers are contrasting the terrorists' exotic European weapons versus the American weapons used by the LAPD, the Steyr AUG assault rifle's bullpup design enables a decent barrel length in a compact design, and it also has an integrated scope. The AUG is used by Karl (Alexander Godunov) during his personal mission to get revenge against McClane after he killed the first terrorist, who happened to be his brother. In a memorable scene of the film, Karl emerges with his AUG in hand.
Steyr SSG 69
Mistaking McClane for a terrorist shooting hostages, FBI Special Agent Johnson (Robert Davi) is seen taking aim with what appears to be a Steyr SSG 69 fitted with an AN/PVS-3 Starlight night-vision scope.
Another weapon in the terrorists' arsenal, an M60E3 machine gun is the weapon used by Alexander to turn Sgt. Al Powell (Reginald VelJohnson)'s police car into "swiss cheese" after McClane throws Marco out of a window and onto the hood of his car. It is also used to shoot out spotlights during the attempted SWAT raid on the Nakatomi building.
The gunner on the Huey helicopter carrying FBI Special Agents Johnson and Johnson is seen opening fire on McClane with a full-sized M60 machine gun.
"Hockey Puck" Flash Bang
During the takeover of the Nakatomi building, the terrorists use flash-bang grenades shaped like hockey pucks to disorient the guard by the elevators long enough for Karl to kill him. One of these weapons is also used during the gun battle that ensues after McClane and Gruber's first meeting when the terrorists are attempting to pin down McClane by shattering the glass windows surrounding him.
Custom Rocket Launcher
When the building is surrounded by the police, Hans has his men set up a custom rocket launcher. The launcher is fitted onto a tripod mount that is seen being bolted down before firing. It's fired twice to take out a SWAT APC.
