Healing

In battle many players will get wounded. You can save them by taking them to the doctor or by playing as a doctor and healing them automatically. If you are not a doctor you can either give them one of your first aid kits or by putting them in a truck or camp and letting others heal them. You can also be promoted medic and heal them. Lastly, you can put them in bunker and let them heal although this takes 5 minutes to do so.
