As a current VCO, I would emphasize that our mission is pretty varied. We cover animal medicine for all branches of the military to include the care of government-owned horses and working dogs and retiree/SM pets too. We also play a big role in food protection to include inspection of food preparation/storage areas on post (which is shared with Prev Med) and sanitary audits of commercial production facilities that sell food to the DoD. The Rabies/Bite Prevention and Zoonotic Disease programs are also in our purview but are not everyday things (at least in garrison). FWIW, we make significantly less than physicians as far as special pays go but do pretty well in comparison to civilian veterinarians. If you haven't already, spend some time shadowing a veterinarian to see if this career field is a good fir for you. Feel free to PM me with questions.
@Ziehl-Nielsen: There were a few days on large animal rotations where I wondered if changing the name of the clinic to "Necropy's Waiting Room" might be more accurate.
Aside: I sometimes lurk to see if the grass is greener on the other side of MilMed (which is how I saw this).
