The care of sick and wounded soldiers has been an important issue throughout history, and the methods for providing medical care to soldiers have evolved over time. In ancient times, soldiers were often cared for by fellow soldiers, with injured or sick soldiers being treated by their comrades on the battlefield or in camps.
During the Middle Ages, religious orders such as the Knights Hospitaller and the Knights Templar were responsible for providing medical care to wounded soldiers during the Crusades. In more modern times, the role of caring for sick and wounded soldiers has often fallen to military medical personnel.
