MSC - MEDICAL SERVICE CORPS is Hospital Administration.
Depending on your specialty - you will be placed in the Corps you are qualified to be in - or that they expect you to become proficient in.
I don't know where you get that "it can mean a lot of things" stuff...
In your case, you say someone is recruiting you to be an MSC (Medical Service Corps) - which is "Hospital Administration" and can be a Resource Manager, a Materiels Officer, a Squadron Commander, etc., all of which fall under the heading "Hospital Administration".
Now, in an AF military hospital, there are Squadron activities (Commander, First Sergeant, Training NCO, etc.) just like in an Army Hospital there are Company units, etc.
The Squadron Commander is usually a 2nd or 1st Lt getting some "experience" in an AF Hospital - at an entry level position - and has to perform the duties for the Hospital just like any other Squadron Commander on an installation - but I assure you, regardless of his/her day-to-day job, his/her "career progression" is via the Hospital Administration [civilian counterpart] ACHE career field as noted above.
Obviously, you don't get to be a "Hospital Commander or Administrator" as a junior MSC officer. You take staff positions such as mentioned and work your way up to the real deal - Administrator of the Hospital.
BSC - BIOMEDICAL SERVICE CORPS is Bio-environmental engineering, and Board Certified Pharmacists, Physical Therapists, etc... (each of whom have their own respective certifications to keep current via continuing education as well)
MC - MEDICAL CORPS - Board Certified Medical Doctors, M.D.s - Board Certified in whatever specialty - Family Practice, Emergency Medicine, OB/GYN, Internists, Psychiatry, Surgery, Radiology, etc., and such... (at junior grades in a teaching hospital may be interns or residents).(each of whom have their own respective certifications to keep current via continuing education as well)
NC - NURSE CORPS - Board certified Nurses, Nurse Practitioners, etc.
DC - DENTAL CORPS - Board certified dentists.
Corpsmen (enlisted) - may be Medical Techs, Lab Techs, Rad Techs, Pharmacy Techs, Physical Therapy Techs, etc.) (each of whom have their own respective certifications to keep current via continuing education as well)
ALL are part of the "Medical Service"... and go into the Medical Service with a "direct commission" and do not have to go through OTS.
You seem to want to make things difficult when there is no difficulty to be had once you know the organization chart of a military hospital - which is very similar to most civilian institutions.
Again, there are not really that many USAF installations - and each typically has it's Clinic or Hospital, etc., with a "medical staff" - all of whom belong to the "Medical Service" and each of whom has their (certifiable specialty).
As noted earlier, this is a close-knitted group of people who all know and work together to provide the best care possible. As such, they typically do things both on duty and off - together and get to know each other very well - families, and such.
I am a Healthcare Architect as well as a Hospital Administrator with Board certifications in both.
The AF Surgeon (and Army, and Navy...) has a small cadre of professionals who represent his interests in the design and construction (via the Corps of Engineers and NAVFAC) of AF Clinics, Hospitals, Dental Clinics, etc. There was no "Corps" for those of us Architects/Engineers so they either put us in the MSC or BSC COrps with a shredout to our AFSC for personnel and promotion.
As such, I not only had my AF progression to worry about, but also ACHE and my ARchitectural Boards and Texas state licensing to maintain.
Before I retired I worked for the SECDEF as Chief of DEsign for DoD - all AF, ARMY, Navy, Marine Corps, COast GUard, etc., facilities fell under my jurisdiction for design and construction... it was a Colonel billitt and I was just a Major. Afterwards, and as a BRigadier, I was the Hospital Administrator of a 486-bed "contracted" military hospital in the Middle East.
As a retired "consultant", I wear whichever hat I choose to get work - usually as an intermittent consultant for the JCAHO - which in this day and age is more and more difficult as one ages...
For what it's worth the COast GUard promotions are (were?) not in the same cycle as the AF, ARmy, Navy, etc., and they get promoted much MUCH faster.
FWIW, Squadron Commander is just about the lowest job you can have as an MSC officer in an AF Hospital and is an entry level position on the org chart. You make it sound like a good job with prestige - har har... - but, it's only as good as your Airmen and NCO's and the First Shirt and the Education NCO...
But regardless, it is generally the entry level in an AF (any military) hospital. From there you might go to Resource Manager, or Materiel (Supply), etc., - all are MSC "Administration" jobs...
And yes, they DO have civilian counterparts - if you get your ACHE, you should have no trouble transitioning from an AF Hospital into a Civilian healthcare setting...
