Definitely consider the Navy - Personnel Specialist US Navy Employee Review

Great for a young person that wants to figure out what they want to do.

Occasional weekend Duty days and deployments.

It is what you make out of it. You'll have good days and bad days. It's all dependent on your leadership. That can make or break the command. Medical is free, but can take a while to get seen. You'll meet a lot of new people and could travel around the world depending on your duty station. Education benefits and training.

Medical can take a while to get seen, unless it's an emergency. If you're single, the pay isn't that great, but you don't have to much to worry about for bills if you live on base. If you're on sea duty billet, your work life balance will be terrible.
