The Theimer Model 21 submachine gun is a blowback-operated, air-cooled, magazine-fed selective-fire submachine gun, invented by Gallian engineer Wolfgang Theimer in 1919. It was originally intended to replace the Gallian MAGS submachine gun, but after the Gallian Army's refusal to replace the latter, it was marketed as a civilian firearm during the 1920s by Theimer.
Despite the MAGS being called a light automatic rifle, in response to Theimer's heavier design, the TM18 Automatic Rifle, The Theimer Model 21 would be the first to be marketed as a "submachine gun".
The Theimer SMG saw early use by the Concordian Armed Forces during the Watermelon Wars against Archadia-Archedes, the Royal Gallian Postal Service, the Royal Gallian Constabulary, the Niflheimian Republican Army, and Alteria. During the prohibition era, the Theimer Model 21 and Model 28 became a signature weapon of various organised crime syndicates in both Concordia and Archadia-Archedes in the 1920s and 1930. It was also used by law enforcement officers and criminals alike.
The Theimer SMG would not be adopted for standard military use until in 1934 by the Lucis Army, when Lucian General Harry Tachibana advised the need for the Lucis Army and other overseas forces to be armed with a small automatic firearm. This move made the Lucis Army as Theimer's biggest customer for the firearm. As a result, Theimer would nickname his creation as the Tommy Gun after the Lucis Army. It became one of the earliest well-known symbols of the Lucis Army during the Second Europan War. Well-loved and liked, it was eventually found in the hands of Lucis Commonwealth soldiers throughout Eordis, being used by Zanarkians, New Akibanders, Rubrumians, Nihhonese, and other Commonwealth nationalities. It was also purchased at large by the Imperial Army of Erebonia. Theimer would later on give the license to produce his gun to Rainford Group.
The expensive cost of the Theimer eventually forced the Lucis Army to develop the SHITA Gun. But despite it, the Tommy Gun saw service throughout the war, as well as during the War of Lorican Aggression until it was retired in 1975. The Theimer currently sees service in certain organisations throughout Eordis, being favoured as a high-caliber submachine gun for defence.
