Ex-Marine, e.g., informally (3)

Ross

I believe the answer is:

vet

(Other definitions for vet that I've seen before include "animal doctor to > investigate" , "Animal doctor, in brief" , "Experienced" , "Examine carefully for suitability" , "Examine, check" .)

I've seen this clue in The New York Times.
