Machine gun

A machine gun is a fully automatic mounted or portable firearm, designed to fire bullets in quick succession from an ammunition belt or magazine, typically at a rate of 300 to 1800 rounds per minute. Fully automatic weapons are generally categorized as submachine guns, assault rifles, battle rifles, automatic shotguns, machine guns, or autocannons.

As a class of military firearms, true machine guns are fully automatic weapons designed to be used as support weapons and generally used when attached to a mount or fired from the ground on a bipod or tripod. Light machine guns are small enough to be fired hand-held, but are more effective when fired from a prone position. The difference between machine guns and other categories of weapons is based on caliber, with autocannons using calibers larger than 20 mm, and whether the gun fires conventional bullets, shotgun cartridges, or explosive rounds. Fully automatic guns firing shotgun cartridges are usually called automatic shotguns, and those firing large-caliber explosive rounds are generally considered either autocannons or automatic grenade launchers ("grenade machine guns"). Submachine guns are hand-held automatic weapons for personal defense or short-range combat firing pistol-caliber rounds. In contrast to submachine guns and autocannons, machine guns (like rifles) tend to have a very high ratio of barrel length to caliber (a long barrel for a small caliber); indeed, a true machine gun is essentially a fully automatic rifle, and often the primary criterion for a machine gun as opposed to a battle rifle is the presence of a quick-change barrel, heavyweight barrel, or other cooling system. Battle rifles and assault rifles may be capable of fully automatic fire, but are not designed for sustained fire.

Machine Gun Kelly

George Francis Barnes Jr. (July 18, 1895 – July 18, 1954), better known as "Machine Gun Kelly", was an American gangster from Memphis, Tennessee, during the prohibition era. He attended Central High School in Memphis. His nickname came from his favorite weapon, a Thompson submachine gun. His most infamous crime was the kidnapping of oil tycoon and businessman Charles F. Urschel in July 1933 for which he, and his gang, collected a $200,000 ransom. Their victim had collected and left considerable evidence that assisted the subsequent FBI investigation that eventually led to Kelly's arrest in Memphis, Tennessee, on September 26, 1933. His crimes also included bootlegging and armed robbery.

Career

During the Prohibition era of the 1920s and 1930s Kelly worked as a bootlegger for himself as well as a colleague. After a short time, and several run-ins with the local Memphis police, he decided to leave town and head west with his girlfriend. To protect his family and escape law enforcement officers, he changed his name to George R. Kelly. He continued to commit smaller crimes and bootlegging. He was arrested in Tulsa, Oklahoma, for smuggling liquor onto an Indian Reservation in 1928 and sentenced to three years at Leavenworth Penitentiary, Kansas, beginning February 11, 1928. He was reportedly a model inmate and was released early. Shortly thereafter, Kelly married Kathryn Thorne, who purchased Kelly's first machine gun and went to great lengths to familiarize his name within underground crime circles.
