Thompson M5

The Thompson M5 is a submachine gun used widely by the United States Armed Forces, including the Space Force.

History
The Thompson M5 is essentially a reinstatement of the historical Thompson-model submachine guns from the 1920s, which saw service in the 1930s and onward before it was discontinued in the 70s. After the anarchist raid on New Boston in 2000 and then the Red Revolt raged on Mars in 2005, the United States Armed forces saw the need to renew its arsenal after decades of peace and stagnation. Thus, a series of new weapons were created and old ones were reinstated and modernized. From this modernization effort came new guns like the R6 Revolver and later the Thompson line of submachine guns, of which the M5 is the current model. Since then, the Thompson model has undergone several changes and reworks over the next decade. For example, the M2 was essentially a copy of the old M1 with updated materials, but it was quickly scrapped after several malfunctions were reported during testing. After responding to these criticisms, the M3 had more success and was in use from 2009 to 2014. It was quickly replaced by the M4, which was then replaced just as quickly the following year by the M5, which is currently in use to this day.

M5A2
The standard M5 model was toned down from its M1 ancestor to make it a less lethal weapon during protests, whereas the M5A2 model is the more lethal version that is derived from the original model.
