Sub machine guns are those guns which have a carbine that automatically loads ammunition from pistol cartridges. Sub machine guns have the firing power of a machine gun but they use the ammunition from a cartridge, like those used in pistols. 

 

 

Ownership of a sub machine gun is prohibited in many countries. In fact, there are only a few countries which allow private citizens to own a sub machine gun. In the United States, gun ownership is governed by the National Firearms Act. There are very specific rules and regulations which individuals must adhere to in order to be permitted to own any gun in the United States.

 

 

 

 

In addition to the regular gun ownership permit, citizens that wish to own a sub machine gun , must also  have registered their sub machine guns prior to 1986. In fact, the manufacturing of these weapons is limited in the United States and no new ownership permits are permitted for those that had not registered the weapon prior to 1986. In addition to the federal law which regulates the ownership of sub machine guns, many states forbid ownership, even if they were registered as prescribed by federal law.

Heavy machine guns are those which are considered the first generation of machine guns, while light machine guns are those more recently invented. The difference between the weapons can be seen in the weight and shape of the gun, as well as the accuracy of each weapon.

 

Heavy machine guns is the term often utilized to describe the machine guns that were manufactured and utilized during World War I. The guns were cumbersome and bulky, making it difficult for soldiers to utilize the weapon. In addition,the bulky weapons were often inaccurate, partly because they were difficult to maneuver. However, the heavy machine guns were able to be fired for long periods of time, because of a water chamber which kept the gun cool. Without the cooling chamber, the guns would quickly overheat, rendering them inoperable.

 

Light machine guns were created so that one soldier could operate the gun independently. The light machine gun is capable of firing in bursts of ten rounds. Soldiers usually have the assistance of a bi pod on which they set the weapon. However, unlike the heavy machine gun, light machine guns did not require that more than one solder be there in order to operate the gun. Light machine guns also fire ammunition which is generally a lower caliber than that which is fired by a heavy machine gun.
