In the United States, 10% of adults have served in the military, yet fewer than 30% of them receive their healthcare from the VA. Once out of uniform, military services members quickly become invisible within their communities and in their doctor’s offices. The very culture of the military calls for humility and caution in speaking with civilians about military matters. This is important because there are critical health implications of military service and, in particular, of deployment that merit identifying those who have served in the military as well as those close to them. This requires asking a few pertinent questions related to their service as part of an effective patient encounter.
