Medics work similiar to a support center except they are lightweight ground units that heal all types of units and heals fusion plants and railguns. They can heal planes, they just need to be close enough. They heal 5 health per second. It is recommended to place medics near the center of an army when attacking.
The medics will heal only things you own, your ally will need their own medic to heal their army.
