Coriolanus is a modern retelling of the Shakespearian tragedy. The original work by William Shakespeare was based on real life Roman leader Gaius Marcius Coriolanus. This is a modern film rendition of an original Shakespeare play, much like Richard III, and was filmed in Serbia utilizing 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.
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.
SIG SG 552
A Roman Legionnaire can be seen wielding a SIG SG 552 carbine when Coriolanus urges his troops to attack.
A Volscian sniper uses a Zastava M76 while battling the Romans. Later, a few Volscian soldiers hold M76s when Volumnia (Vanessa Redgrave) and Virgilia (Jessica Chastain) visit Coriolanus at the Volscian camp.
A Volscian escorting Volumnia and Virgilia holds a Vektor R4 rifle, distinguishable by its bipod and lengthened handguard.
