Weapons used by the USCMs were constructed from real fully functional weapons. Armourers used guns they found to be the most reliable when firing blanks and those which looked futuristic. Pulse Rifles were built from a Thompson SMG with an attached forend off a Franchi SPAS-12 shotgun and a Remington 12 Gauge Model 870P receiver with barrel.

One live fire pulse rifle referred to as the 'hero' version was one of the few practical guns used on set, there were only 3 or 4 live fire weapons required for filming but hero was the only one that had both built in firearms functioning. A large number of lightweight fibreglass pulse rifles were also required for use as the live fire version was quite heavy. Flux versions were also used for background filming and as set dressing and had the added advantage of not requiring an expensive armourer to be on set when the real guns were not in use.


In filming weapons fired blanks and plastic bullets similiar with air-shots with the FX being added in post production for both sound and muzzle effect.
