Lazer, I would strongly recommend that you step back and look at what exactly you want to do. If you want to be a 'medic' in the 'tactical' sense, you've got three options.
1. Join the military, active-duty. Not a bad gig, and as a male you've got a decent chance of ending up in an infantry unit, but with the current budget situation, I strongly suggest that you not make this your primary bet.
2. Join the military, reserves. It's a decent compromise, but it's not quite going to be your best option.
3. Law Enforcement: If you want to get out and do 'tactical' stuff with less of an emphasis on medicine, look into law enforcement with an outdoor emphasis- Fish and Game, Forest Service, etc, or possibly a municipal department or county sheriff. It's going to be better pay and will realistically get you closer to 'tactical medicine' than being just another wannabe EMT.
Look at it this way. There's lots of underemployed and unemployed EMTs and paramedics who want to be 'tactical medics' and live up the perceived adrenaline rush that my generation's veterans have. There's also lots of unemployed veterans who have prior combat experience (and many of whom also hold EMT certification) looking for law enforcement/ SWAT/ 'tac medic' jobs because it's one of the few things that military training and experience carry over into. This is only going to get more pronounced as the force shrinks.
Getting to what you tell us you want via medicine is possible, but it's not anywhere near as easy.
