Pets, wives, and privacy are things you cannot count on keeping or even bringing into the military. Most pre-military marriages end in divorce because they have NO idea what they're getting themselves into. Family will never, ever come first. Doesn't really matter what's happening on the home front, whether you work too much, etc.That's not necessarily true. Some bases require you to be E-3 (E-4?) before they'll let you off-base to live. Exceptions are made for families though. Not sure about pets.
My last six months I was pulling 16 hour shifts (really 17) every day of the week. I can't imagine how that would've turned out with a wife and kids.
