The Military is what you make of it. Not for everyone but a great milestone to reflect upon as you get older. Sure enough will dry your ears out bud and get you out of ordinary life for a bit.
As far as a specific branch for the desired job... do your homework and check for incentives and offered training that each branch might offer to find the best match.
Lil tip don't ask any of us what branch is the best. We all have our favorite and will usually fight to the death to defend it.
