Really depends on your AFSC (job code), unit and era. I was in one of the more infamous career fields (Security Forces), and the running joke was that we were "real military" compared to the rest of the "Corporate Air Force". A lot of maintainers I knew had similar sentiments towards other office-based career fields.

And that was only at a stateside base - the dynamic got really weird when we deployed on in-lieu-of taskings to relieve understaffed Army units in Iraq. Their Military Police had a similar level of intensity as us, but most of their rank-and-file in the role were augmentees pulled from other career fields without a law enforcement background.
