Wonder Woman is the 2017 feature film adaptation of the popular DC Comics series of the same name. Gal Gadot stars as Diana, an Amazonian demigod and daughter of Zeus previously introduced in 2016's Batman v Superman: Dawn of Justice who finds herself leaving her home and experiencing the outside world when she meets Steve Trevor (Chris Pine), a U.S. military intelligence officer in the US Army Air Corps. The majority of the film takes place during World War I with bookends set in the modern day. Directed by Patty Jenkins (Monster) and produced by Zack Snyder, Wonder Woman also is part of the Worlds of DC, which includes Man of Steel, Batman v Superman: Dawn of Justice, Suicide Squad and Justice League. Gadot would return in the 2020 sequel Wonder Woman 1984.
The following weapons were used in the film Wonder Woman (2017):
Steve Trevor (Chris Pine) carries an M1911 pistol as his sidearm throughout the film.
Rifles
Mauser Gewehr 1898
The mainstay rifle for the German Army for World War I, the Mauser Gewehr 1898 is seen in the hands of German troops who engage Wonder Woman. They are seen both with and without bayonets. A German soldier is also seen with a scoped Gewehr 98. The rifle also is seen in the hands of Steve Trevor (Chris Pine).
A scoped M1917 Enfield is used by Charlie (Ewen Bremner). It can be distinguished as an M1917, rather than a .303 P14 Enfield, by the longer grasping grooves on the stock.
Lebel 1886
French soldiers in the British trench armed with Lebel 1886 rifles.
Turkish 1903 Mauser
German and Turkish soldiers can be seen with 1903 Mauser rifles.
Winchester Model 1866 "Yellow Boy"
A Winchester Model 1866 "Yellow Boy" is carried by Chief Napi (Eugene Brave Rock). Note the brass studs hammered into the buttstock. This is an accurate cultural affectation for these rifles by Native Americans.
Machine Guns
Maxim MG08/15
German troops use Maxim Maxim MG08/15s in trench warfare. It is also seen mounted on a German Ehrhardt E-V/4 Armoured car which is unusual because the Ehrhard was armed with Maxim MG08s.
Maxim LMG 08/15 "Spandau"
What appears to be Maxim LMG 08/15 machine guns are mounted on warplanes.
Lewis Gun
Lewis Guns appear both dismounted in the hands of British soldiers (including the one portrayed by Zack Snyder in a cameo) and mounted in British Mk IV "Male" tanks. A Mk IV tank with "Iron Cross" markings can be seen at the German base during the finale, which is actually somewhat accurate as a number of British tanks of various marks were captured and used by the Germans during WWI. The Mk IV tanks in the film lack the unditching beam and rails, which is incorrect as all Mk IV tanks deployed to the western front were fitted with these (however training tanks and tanks deployed to the Middle East did omit this system).
A bundle of Model 15 Stielhandgranaten attached to a tomahawk is thrown by Chief Napi (Eugene Brave Rock). Ares uses his powers to throw a entire crate of them at Wonder Woman in the final battle.
Wurfgranate 15
After capturing a German plane, Steve tosses a Wurfgranate 15 grenade into the factory. Although originally intended for spigot mortars such as the Granatenwerfer 16, Wurfgranates were actually carried by German pilots for aerial bombing. However, in this role they were generally carried nose up in a rack secured by the safety pin in the fuse as opposed to nose down in bins as portrayed here (although this is the method by which Stielhandgranate were carried in the same role).
