Hey. As a medic in the Army you could be doing such a wide variety of things and be assigned to any number of different types of units.
In a clinical setting you could be doing vitals, triage, blood draws, iv's, cleaning the waiting room, filing, cleaning the bathrooms, starting IV's, answering the phones, making appointments...any task that needs to be done that you are assigned to. On some of the smaller posts there isn't a hospital, so all the soliders have is a walk-in clinic setting, where anything else gets sent miles away to the hospital.
In a hospital setting you most likely would just be doing triage and answering the phones, possibly working on the ambulance, if they have their own. But with the Army you never know, they can cross train you into anything.
Medics assigned to companies other than a Medical Company (or detachment), such as an infantry or engineering unit may work out of the clinic when they are not deployed or in the field.
Its really hard to say what exactly you'd be doing. It will all depend on where you are assigned, what kind of command you have, what type of company you are assigned to, what kind of solider you are, whose *** you kiss, who you piss off, ect.
There is opportunity to learn things and do things under the protection of the Military that you wouldn't be able to do as an EMT working for a civilian EMS service.
So, any of you other military medics have any other ideas.
Understand, I was not a Medic in the Army. I was Intel (and yes I know thats an oxymoron
), however these are observations and things I learned from friends growing up in and being in the Army.
