The Thompson Sub-Machine Gun (also known as a Tommy Gun) that was popularized in the 1930s by Al Capone and other gangsters. It has decent stopping power, a fast reload time, and is the only machine gun on the island. Less popular than the revolver among COs, but a frequent weapon nonetheless.
An old favorite, this machine gun can hold its own despite its age. Ammunition is more rare than the Skorpion, but its power is greater; though it is much weaker than the M-60.
