I had two Army physicals in ROTC, the first one was at Fort Sam Houston with the rest of my ROTC class. The previous year the juniors headed to Fort Sill were given shots with the "humane" air gun. Most of them could not use their left arm for a month. So thankfully the university nurse gave us ours. The boys who wanted to fly had flight physicals, which included prostrate exams. As we young men were then ignorant of the significance of that vile organ there was much speculation as to the reason for the digital penetration. The general consensus was that it must have been done "...to see if you like it, I guess..."
The second one was at Fort Sill six months later, just in case Fort Sam missed anything.
In my freshman year of dental school (1971) I had a 4 striper uncle who had the Legion of Merit and offered to get me in the Navy. Sounded good. For some reason two other dental students, one prospective Navy early commission and one Air Force, went with me. I mused about whether I should wear my Army 2Lt greens. "Naaaw... You don't want to wear an Army uniform to a Navy interview!" Was their opinion. When we arrived we were treated like everyone else, like cattle. It was kind of a blur. There was the "Turn your head! Cough!" command. I don't remember if the doctor changed gloves between examinees.
Finally came the time for my medical history question answer to be scrutinized by a bored Navy LT medical officer. "Alright, I see you checked 'yes' to 'tumor or cancer' - what did you have?"
"An old aseptic necrosis of the second right distal metatarsal." I answered (translation: oddball bony growth in foot).
"Where are you in school?" I told him Baylor dental and he wanted to know if there were any others. After that we were real well treated. All in all I think it would have helped had I worn the boot brown bar outfit. There we sat, on the group W bench....
The "Navy" thing worked out differently than I thought, wound up spending two years with the Marines and going on the 1975 Vietnam evacuation as an infantry battalion (1-4) dental officer. At the time it was very intimidating but in retrospect a great experience.
