Combat_Medic, firstly, I seriously doubt the USMC policy states that all members are "soldiers" first, I strongly suspect that they are "Marines" first, tradesmen second. Call a marine a soldier and see how he reacts.
Secondly, we need to look to the skills required on deployment, and identify the time-lines necessary to make a medic deployable. If we can teach and/or refresh "army" skills faster and cheaper then "medic" skills, the obvious answer is that, in peacetime, we teach medical skills and bridge with the "army" skills as required; If the opposite is true, we do the reverse: teach "army" and bridge to medical skills.
It may be most beneficial to have both programs running concurrently, teaching FEBA-type "combat" medics the medical skills they need pre-deployment, and teach the high-end medical specialists "REMF" medics the "army" skills they'll need prn.
The future of armed conflict is theorized to be both the "three-block war" and a come as you are conflict; the latter precludes a lot of build-up/work-up, and obviates the reserve force to a large degree; the former calls for a cross section of skills with different focus in different phases.
If we take as a starting point a civilian paramedic, we can, according to the overall tng plan, turn him into a soldier with BMQ/SQ and a military medical orientation, about 10 weeks in total. Take that same person, but without being a paramedic, and it's 10 weeks to being a soldier, 13 weeks to being a paramedic (not including pre-study, a&p, etc), and 16 more weeks to be clinically trained. The delta, from paramedic to soldier, is about 10 weeks, from civi to paramedic to army medic is 39 weeks plus some actual clinical exposure and patient care experience.
The tactical combat casualty care course is good, will save lives, and has undoubted benefit, but it is not a replacement for a trained prehospital professional; it is the actions that professional takes under austere and dangerous conditions to save lives. It is a standard of care appropriate for a hostile environment.
As far as medics teaching wpns etc, the philosophy is that if you can teach, you can teach. Once you know a skill, you can teach it. You don't need to be an Infantry Sgt to teach MG theory, you just need to know it. IST is there for a reason. If you've got 3 infantry MCpls and 3 CSS MCpls, guess who should be teaching the class?
In response to your comment about leading section attacks etc on PLQ, the point of PLQ is to test you leadership, not your infantry skills. Infantry skills are the great equalizer when you're not teaching ISCC; everyone needs to be familiar with them, not SME's. We all have stories about the tactically dubious maneuver that results in a PLQ PO pass, BECAUSE THE CANDIDATE DEMONSTRATED A KNOWLEDGE OF THE PRINCIPLES OF LEADERSHIP, APPLIED THEM, AND LED HIS TROOPS.
The gunner given the small party task of evac'ing wounded from the minefield didn't prod properly, didn't prove the ground, didn't immobilize the blast-injured patient, but he lead his section using sound planning and leadership and got the patient out with the resources available. Would I want him as the med pl QRF IC? no! Would he want me laying his guns? NO! did they each demonstrate and apply the principles of leadership in a military setting? Yes.
We turn kids into soldiers without a problem, we just can't seem to turn them into both soldiers and health care professionals at the same time.
