Not related to this subject...but one base I was at had an E-6 Dental Tech who was an actual DDS a Dentist and practiced part-time at an office off-base.

As I understand it, he got his DDS later in his career and didn't want to do the 10-years commissioned or whatever...so was finishing out his 20 enlisted and planned to go full-time civilian Dentist after retirement.
