Every area of the world has its own set of threats. In the United States, we're familiar with the flu and colds, with some regions host to poisonous snakes and spiders, and areas of extreme heat and cold. American military units face deployment in almost every corner of the world at one time or another, so field medics are trained in how to treat problems. For example, the tropics are notorious for myriad exotic diseases, while winter in the mountains can bring frostbite in seconds.
Likewise, combat often takes place in the most remote of locations, far from any kind of permanent medical facilities. Getting the wounded soldier away from the line of fire is just the first step. Finding transportation for casualties to a medical care facility, and getting them there quickly, can dictate whether the patient lives or dies.
In both cases, the challenges for the field medic are to be aware of the local threats to soldiers in the way of diseases and knowing how to get patients to the care they need.
From what we've seen so far, being an Army field medic is no walk in the park. How do they deal with all of this psychologically?
