What MissMowgli (Heather) said is probably the best advice anyone could give you as far as the Air Force goes. Everything she said is on point and couldn't be said any better.

One thing to remember. Yes the recruiters are there for you, but remember they are there for themselves first and foremost. They need you. They will tell you whatever you want to hear to get you in. It's all about numbers and quotas. They have to make quota or they look bad. They also get paid more money to be recruiters. If they can't maintain, then they gota move on and go back to a regular assignment. It is never too late to walk out. You can even walk out the second you get to boot camp.
