Disclaimer: I am a pre-med student with both limited knowledge of the medical profession in its various disciplines and military service in general. The extent of my information comes from my father, an M.D., and two close Army ROTC friends of mine at the university. Don't laugh in my face or be preachy, just give me some honest and polite answers and opinions. No doubt my preferences will change in the upcoming months and years anyway. Okay, to the meat. One day I hope to be a doctor (of unknown specialty). My motivations? The financial security is nice but mostly it's humanitarian. I like to help people and learn about the larger human condition. I like a little adventure (i.e. learning Arabic at the moment), so never thought I would just get married one day and enter private practice in a nice nuclear household with 2.1 kids. I imagined that I would join Doctors without Borders, or at least travel to developing countries a few times a year to do humanitarian aid work. My ROTC buddies have piqued my interest in the military. Obviously I (and they) know that I don't want to kill people, am not *gung-ho* patriotic, and aren't into the usual, stereotypical manly things (guns, porn, red meat). But when I heard about the USNS Comfort and USNS Mercy traveling around the world--treating U.S. and enemy soldiers while going on humanitarian missions--I had to look into it further. So basically I'm wondering: Hypothetically, one day far into the future I leave residency and am dissatisfied with starting my own practice. If I joined the Navy, how much choice as an officer do I have in choosing where I want to be stationed (USNS Comfort/Mercy)? Or will this choice only come after X years of service? The idea of traveling the world while helping to save American and others' lives, learn about foreign cultures and languages, while sailing the open seas, is a appealing one. Has anybody ever thought about this? Am I idealizing and romanticizing this too much or am I on the dot? Thanks in advance. Edit: Fixed.
