Although I was in the Air Force, when it comes to some jobs, all the services are all pretty much the same and require all the same qualifications and have the same duties - Especially in the Medical Field such as what you are talking about.
In the Military you have Clinical Social Workers - in which you would need to have at least a Masters Degree to qualify, a Bachelors in Social work will not qualify you for the military Clinical Social Worker program. The services also have Clinical Psychologists in which you would have to a Doctorate - either a PsyD or PhD.
Those were the Officer Programs - the doctors. Now you have the Technicians, the Enlisted folks that will be assisting the doctors.
