Pros
The Air Force offers top-tier training and outstanding educational benefits to those willing and able to take advantage. I received a Master's Degree from an ABET accredited university with less than $250 out of pocket expenses. Travel can be a great opportunity, but the options available will vary widely with your career choice. The Air Force offers a highly structured environment with equal opportunity for advancement.
Cons
You will be deployed away from your family. There is a high probability you will not get assigned where you'd like to be stationed. The amount of "additional duties" will probably eclipse your primary job. You may deal with less-than-charismatic "managers" whose focus is not on taking care of their people, but taking care of their own career. You have to take a PT test, but if you weren't expecting that-the military probably isn't for you.
