Musicians travel all year long though for parades and ceremonies and what not... ALL trades are going to be subject to travel abroad at one point or another...
But yeah... Sirux0r, from reading your other posts so far all I've found is whining about the military, administrative problems, trying to buy issued military kit that you are not entitled to, (which for the seller would be illegal) and you state you've been in for only a year and a half...
First I want to say... good on ya for trying to get help with an alcohol problem (even though it seems you claim the military is to blame for it)
Secondly, before even thinking of the issues about re-signing your contract... realize you still have 2 and a half years of your VIE left (you stated your initial commitment was 4 years?) This means you have less time in than you have time to go... We all know the Military life can be difficult, and sometimes it downright sucks. However, if you're really this concerned about your career at this stage of it, perhaps you'd be doing yourself, and your co-workers, a great service if you released.
Just my 2 cents, take it for what it's worth.
