Civilian v. Military TCCC Careers

So, I'm going to be out of High School soon and considering whether or not I should do military or a civilian career. I know I don't have to decide at 18, but I'd like to decide around 18-22.

For me, the military is the largest opportunity and closest to what I want from a career, and likewise the largest commitment.

So I'm curious, is there any TCCC careers in the civilian world that will ever supplement what I want from the military? I'm not against the military at all, and it is still a very large choice for me, but it is probably one of the biggest commitments someone can make. I'm interested in SWAT Medicine, but it requires a lot of experience/certifications and is one of the more selective careers.

I understand there are paramedics and EMTs, but I don't think that's what I'm looking for necessarily? I view that less as TCCC and more as emergency medicine, given you're usually not apart of the combat and only acting until the entire scene is cleared.
