Medics, do you get more training in the hospital or Out on the line? if you had a choice would you work in a hospital or out on the line?
The vast majority of my medical training and knowledge came to me after I arrived at my first unit, not at AIT. Combine an awesome PA with CMAST and BCT3, and you can have a line medic that will be able to perform drastically above and beyond their normal scope of practice/68W10 skill set.
I worked with 66W(Medics) mostly in the hospital. They are mostly of use in the ER. Problem with fixed facilities like Brooke Army and Walter Reed is they are credentialed by the Joint Commission so the scope of medics working in CONUS is very limited vs working in the field. This is the number one frustration voiced to me by the medics I've worked with. It is a legal thing so there is no getting around it. Working in the hospital they will get exposed to a greater variety of things, and it serves as a better teaching (Knowledge) environment. That being said, the field allow medics to do their actual job. A medic's job is to be with their troops and to care for them. I think fixed facility is just where you keep them between wars or to give them a break between deployments. Most of the medics I know would rather be in the field.
The Army did our medics a favor vs the other braches. Every Army medic (68W) is an EMT (Emergency Medical Tech). The next step up, the 68WM6, have gone to addition schooling to become LVNs (Licensed Vocation Nurse) - The LVN has much more use in a hospital because the hold a license from a state nursing board. The LVN has a bridge to RN, which allows them to get a commission later.
The medics I've met from both the air force and navy, after they got out of the military had no civilian recognized training. Which was an area of frustration for them, they were qualified to be a nurse's aid as far as hospitals were concerned.
My comment about civilian validation has mostly do with the air force. There enlisted medical personnel did not receive EMT certifications or LPN/LVN licensure. When they left the military, they had no civilian transferable certifications to fall back on.
