The Hospital is a Building in Empire Earth that can heal all units except for Aircraft, Cybers, Ships, Submarines and Space ships. It is available in the Copper Age right up to the Nano Age. Clicking on it will display the range it has in which units must be in to heal. In the beginning stages units should be placed in it to heal, while in the later stages the area is large enough for it to cover a strategic battle location. It can heal multiple units at the same time, but is much slower compared to a Strategist Hero's healing rate. It can also prevent units of dying of Plague, as the calamity's health drain is slower than the Hospital's healing rate.
