During the Gandhi II trailer, a street thug is seen with an unidentified revolver.
Heckler & Koch MP5A3
During the Ghandi II trailer, Gandhi (Jay Levey) is seen using a H&K MP5A3.
Norinco Type 56
During the Rambo parody near the end of the movie, George ("Weird Al" Yankovic) imagines a stereotypical action-movie villain who shoots at him with a Norinco Type 56.
Browning M2
Two Browning M2 machine guns can be seen during the Rambo parody, the first mounted on a jeep, the second behind a barricade.
AK Variants
A group of soldiers armed with Kalashnikov rifles are seen near the end of the Rambo parody. As we are never given anything other than a long distance view of the weapons, it is impossible to determine if they are genuine AK-47s or AK clones.
M60 Machine Gun
During the Rambo parody, George ("Weird Al" Yankovic) uses an early model M60 machine gun (Rambo's iconic weapon from First Blood). The muzzle flashes were obviously added post-production, as he uses it without any sort of ammunition.
Colt Gold Cup National Match
The "action movie villain" makes one last attempt to kill the Rambo-spoofing George with a Colt Gold Cup National Match.
