After the second copy, the soldiers attached a blood-returning skill, which slowed down after use and consumed ammunition.
The medical station in the bunker is only to save the dead soldiers. There will be a white note in that medical station, and when it is full, a team of grenadiers will be sent.
German armored elite:
The headquarters upgrades the defense plan, and then all base buildings and civil building outposts will automatically help people around them to return blood and speed up the recovery of consumption skills.
Armored elite has no medical station.
United States:
The medical center built by engineers (which can only be built in the base) can help people around to return blood.
The medical clinic built by the infantry squad is the same as the bunker of the medical station of the German Defence Force. It only helps the wounded. When enough people are saved, send another batch of infantry classes.
Britain:
Medical stations built by infantry units are usually the same as those built by the United States and the German Defence Forces. It only helps the wounded. When enough people are saved, an infantry team will be sent.
However, the British medical station has a skill that can give blood back to the surrounding soldiers in a short time (with a halo display) after opening, but it will consume ammunition.
