I think the UAV job will offer far less glamorous travel and intrigue than you hoping for. Your travels will most likely end up in the Middle East area. That said, if you are looking for something new and different, give it a shot. You are only young once and, if you don't like it, you can move to something different. You sound like you want an adventure and the military (you'll almost be in it) provides plenty of "adventure."

I would plan on a lot of time away from home. You need to check with the POC to find out what the requirements will be. At this time, I wouldn't be overly concerned at danger/bodily injury, but it can always happen. You aren't signing up to patrol streets or drive in convoys. For those of us in the military, one of the biggest drawbacks is time away from home. You never get to replace this time. When you have limited responsibilities (no wife and kids), time away usually isn't that big of a deal. I don't know how time away will effect your girlfriend, but it seems it usually doesn't work out for many. Anyway, your next step should be a phone call to the POC. Have your questions ready and if you get a bad vibe, maybe it isn't the right time for you to make a change. There are other ways to find adventure too.
