The gun was 3 feet 8 inches (112 cm) long and its cyclic rate of fire was between 450 and 600 rounds per minute. In practice, it was expected that 10,000 rounds would be fired per hour, and that the barrel would be changed every hour—a two-minute job for a trained team.

The L7A2 General Purpose Machine Gun (GPMG) is a 7.62 x 51mm belt-fed general purpose machine gun which can be used as a light weapon and in a sustained fire (SF) role. In the SF role, mounted on a tripod and fitted with the C2 optical sight, it is fired by a two-man team who are grouped in a specialist Machine Gun Platoon to provide battalion-level fire support.

Despite being known best in the commercial market for handguns, Star's primary business has been in many ways their military submachine guns. The fall of the SMG in the 1980s to the 5.56 mm carbine may even have been a contributing cause of their eventual demise.

For example, in 1912, the United States Army only issued four machine guns per regiment but by 1919 the number increased to 336 machine guns per regiment. The machine gun allowed soldiers to rapid fire bullets at the enemy at a rate of 400 to 600 rounds per minute.

The cyclic rate of fire with the machine gun is achieved when the trigger is held to the rear and ammunition is fed into the weapon uninterrupted for one minute. Normal cyclic rate of fire for the M249 is 850 rounds, M60 is 550 rounds, and for the M240B it is 650 to 950 rounds. Always change the barrel after firing at cyclic rate for 1 minute.

The UZI is an infamous SMG because it is very light and has one of the highest rates of fire of any weapon. A Submachine Gun (abbreviated SMG) is a weapon that often combines high rate of fire (with the exception with the unusually slow UMP) and portability to build the perfect weapon for covert and stealth missions. SMGs offset this exceptional rate of fire with reduced accuracy at longer.

Ammunition planning is in doctrine in the ATP 3-21.8 dated April of 2016. The first thing you must know is what the rates of fire are for your specific weapons system. Pictures one and two illustrate the sustained, rapid, and cyclic rates of fire for our machine guns.
