Foremost among the many problems that can compromise your survival ability are medical problems resulting from unplanned events, such as a forced landing or crash, extreme climates, ground combat, evasion, and illnesses contracted in captivity. Survivors have related feelings of apathy and helplessness because they could not treat themselves in this environment. The ability to treat yourself increases your morale and aids in your survival and eventual return to friendly forces. One man with a fair amount of basic medical knowledge can make a difference in the lives of many. Without qualified medical personnel available, it is you who must know what to do to stay alive.
