Tricare is great, GET ENROLLED. They pay all medical expenses that you may incur. I didn't expect to have much to worry about but sometimes you get things in life you don't expect. Tricare has paid out a ton of money on my behalf and there is zero personal responsibility. Get off of you parents' policy and get your own, you will definitely save them money. It takes some effort on your part but it's well worth it.
All you do is fill out the Tricare enrollment form that your recruiter should give you. You'll get a Tricare insurance card, and when presented with an active duty ID card you get free medical care. The one catch is that you have to go to a doctor who particapates in the Tricare network. Call the 1-800 number for Tricare (on the enrollment form) and they can answer your questions.
