Editing Submachine gun (section)

===1960s===
In the 1960s, [[Heckler & Koch]] developed the 9mm Parabellum [[MP5]] submachine gun. The MP5 is based on the [[G3 rifle]] and uses the same [[closed-bolt]] [[roller-delayed blowback]] operation system. This makes the MP5 more accurate than [[open-bolt]] SMGs, such as the Uzi. The MP5 is one of the most widely used submachine guns in the world,<ref name="hogg2002">Hogg, Ian (2002). ''Jane's Guns Recognition Guide''.

In 1969, [[Steyr AUG|Steyr]] introduced the [[MPi 69]], which is similar in appearance to the Uzi SMG.<ref name="Century 2000. pages 97-98">Military Small Arms of the 20th Century. 7th Edition. by Ian V.
