A Submachine Gun, often abbreviated as SMG, is a type of weapon in the Call of Duty series, appearing in all games. Submachine Guns make a bridge between a Light Machine Gun and a Pistol, having the fire rate of a Light Machine gun, while having the mobility and range more similar to that of a pistol. Submachine guns are some of the most common weapons in Call of Duty, with games all having a variety of SMG's depicted in-game.
The majority of SMG's suffer from odd inaccuracy traits, such as enhanced idle sway or a minor amount of bullet spread while aiming, similar to that of a Shotgun, alongside poor bullet damage at a distance. To compensate for this, the majority of SMG's have a very fast strafe speed when aiming down the sights, at least moderate rates of fire, and good hip-fire accuracy, making the SMG's ideal for close to medium range combat playstyles. Some SMG's, however, have stats that will mirror Assault Rifles, such as range and accuracy, while sacrificing some key SMG benefits, such as power and rate of fire.
