History's armies lost more soldiers to disease than to combat — and the Army wrote the book on not letting that happen. Water treatment and disinfection, waste disposal, food safety in the field, insect and rodent control, heat and cold injury prevention, even poisonous plants. The unglamorous knowledge that actually keeps a camp, homestead, or group alive long-term.
