Coriolanus is a 2011 film, a modern rendition of William Shakespeare's tragedy, based on the real-life Roman general Gaius Marcius Coriolanus, who leads a successful campaign against a rival Italic tribe, the Volsci, but is alienated by the internal politics of his home city. Filming took place in Serbia and (similar to 1995's Richard III starring Ian McKellen), utilized modern settings and weaponry.
The following weapons can be seen in the film Coriolanus:
The SIG-Sauer P226 appears to be the standard sidearm of both Roman and Volscian forces in the movie. Tullus Aufidius (Gerard Butler), leader of the Volscians, uses a P226 to execute a Roman prisoner. Coriolanus (Ralph Fiennes) later uses a P226 while single-handedly storming a building during the battle in Corioles.
Rifles
Colt Model 933
The Colt Model 933 carbine appears to be the standard infantry weapon for the Roman "Legionnaire" forces, used by Caius Martius Coriolanus (Ralph Fiennes) and his fellow troops. All of the M933s in the movie are fitted with M68 Aimpoint red dot scopes, and some of the rifles are also missing their front sights.
Zastava M70AB2
Tullus Aufidius (Gerard Butler) and his fellow Volscian soldiers are mainly armed with Zastava M70AB2s throughout the movie. It appears to be the standard Volscian infantry rifle.
