The previous poster is absolutely right- there is no typical tour! My cautioning I guess came from an enlisted man's wife... and if you might meet someone, how that might affect her. However, I've also seen him evolve as he's been in, and he has grown to dislike it immensely *not saying that you might not love it* I don't know what it would be like for a pharmacist, but I guess what I'm trying to say is that you SHOULDN"T take anyone's word for how it will be (recruiter, anyone) without talking to someone that has been there, done that with that branch of the military. Recruiters especially have a way of looking at things through rose tinted glasses, then convincing you to sign up... but once you've signed, it has nothing to do necessarily with the recruiter or what they told you. My husband did a tour in Korea with a guy that worked in the pharm (might have been a pharmacist, my husband isn't really clear on the civilian classifications, ect.) and he certainly was treated no differently than "Joe" the typical soldier.
To address something else from the PP, yes, my husband and I had a choice about where he went- germany for three years or korea for one year. I'm here working on a graduate degree- I'm not going with him, so we chose korea. If that's what you mean by choices, yes, we had those presented to us.
Also, my husband is enlisted (E7) and we have always had to request permission and leave notice for leaving, even for a short period of time.
But again to agree with the pp, it will completely depend on your situation and what you want to happen...
so, good luck with your choices!
