Tactical EMT-B/EMT-P is a local thing, as far as I've seen EMT-T isn't even a "real" certification, but more of a title bestowed upon CONTOMs grads. There are no protocols for EMT-T, and from what I've seen, you won't get a state cert/nat. cert with EMT-T. Last I checked, CONTOMs is still running, but may be under a different acceptance policy, as they are now under the Dept. of Homeland Sec. and I think ICE. My suggestion for LE is to get your EMT-B which apparently you have, and then wait for them to send you to school. You've got 3+ years of patrol rotation before you're even eligible for SRT/SWAT/ERT/etc... generally. I don't mean to shoot down your dream here, but it is a difficult road, and other than some minor differences, tac-med in a SWAT environment is more about the tactics, and less about the med. Care for bullet wounds is nothing more than care for penetrating trauma, bleeding control, supplementary fluid, pain control. Blast trauma with High Explosive is a little different, because you have to understand the blast wave and overpressure, but if you're a good medic, you already have the tools, you just need a little "tweaking." Also, unless you're active duty military or LE, you won't be accepted to H&K, that is a fairly recent development, thanks to an incident about 6 mo ago. Are there good tactical medicine courses out there, absolutely, and if that's your interest, by all means, but it may be a while before you get to practice the cool guy stuff. B) Oh, and if you're interested, I have a few things on blast trauma, since I've been studying up on IED/VBIED lately for my next deployment.
Best of luck
