Each of these promotions costs 1 promotion point. Level 3 promotions are unlocked if the player received his third promotion in that specific match, and level 5 promotions are unlocked if the player received his fifth promotion. If a certain support power has multiple levels, higher levels require lower levels to be unlocked first, and when they are, they replace the lower level variant.
The United States of America has an army comprised of expensive, but high-tech units. Despite their price, they try to accelerate the rate at which they gain experience. Their arsenal covers all fields almost equally, while their air force is the strongest compared to that of their adversaries. USA vehicles are highly adaptable and can attach drones to increase their defensive capabilities.
