Good writing includes creating unique, independent, memorable characters. Here, we have two sisters who are so similar that they think of themselves as interchangeable (Right down to wearing the same style of clothes and hairstyle). Yeah, that sounds like a spellbinding story element.
OK, there are no medics in the Navy, they are Corpsmen. Any brother of a corpsman would likely use that term. Corpsmen not only serve at shore-based hospitals and onboard ships; they also accompany Marines into combat. So, they are involved in everything from drawing blood and giving vaccinations to treating trauma such as from industrial accidents and hostile weapons fire. Think of them like an EMT except more independent; often they can’t transmit vitals to an MD and receive instructions … they are on their own. It isn’t frequent, but corpsmen have been known to perform surgeries, such as appendectomies, when the patient needed immediate attention and time was insufficient to move them to a hospital. Ships like submarines, for instance, aren’t large enough to carry an MD.
Why is it we continually see Fred roaming the city with his pals, then begging to be taken for a walk? If he wanted to go out, he seems to be free to go!
I relate to this, when I was in the Naval Reserve it seemed like there were always people unable to do the physical fitness test because they hurt themselves preparing for the physical fitness test.
Hey, it was only 6 below this morning … that was REALLY invigorating!
