Game description from the publisher:
The SSU Close Combat Squad provides versatile new soldiers for your Dust Tactics army. After fighting in many intense close-quarter situations, the soldiers of the SSU have become experts at this type of combat.
Well-known for their ability to craft makeshift weapons like Molotov Cocktails, the SSU Close Combat Squads form a large part of the SSU forces. These grizzled squads carry Shotguns and a Flamethrower for maximum damage at close range, and to increase their effectiveness, they have learned how to scout out prime locations on the battlefield.
