The United States of America (USA or United States) is one of six subfactions of the Allied Nations in version 2.0.
Americans count on their sneaky, ambush-oriented, but also powerful units. During battle, they like to attack enemies suddenly and brutally, which is why they have decided to improve their assault technology and create powerful tanks that all armies are aware of.
