I spent six years in uniform resenting it. It is discrimination. Killing people, even for a good cause, is not an adventure. Read the fine print on the enlistment agreement. Nothing is guaranteed.
Travel is possible and much more enjoyable as a civilian.
Many overseas assignments are hellholes, and the local people regard foreign troops in their midst as either a plague or a bunch of suckers. I've been there. Your training will very likely be worthless. Think about it. They misrepresent the amount of money you can get for college, and your service makes you ineligible for other more lucrative grants and loans.
