The Ronin is one of the most formidable infantry units in the game. Able to go toe-to-toe with most vehicles, and heavy enough to shrug off a lot of damage from infantry too. Their Gauss Carbines give very strong anti-tank firepower, but they can instead replace them with Bio-Atomisers and Energy Blades, turning them into a pre-eminent close quarters unit that can clear out a room in no time.
