I could add something from the clinical perspective, as someone who has worked in the civilian system as well.
It's commonly quoted that approximately 40% of family practice visits are for overt mental health problems. Mental health problems are the bread and butter of what family practitioners do. It is the family practitioner, the general duty medical officer, who does the periodic health assessment every two years. We are very sensitive to it. We both actively and passively will pick up on most mental health problems in that situation.
