That is indeed what they are saying.
For the most part, tactical training is a money maker. It will be very rare to find the position as your sole source of employment or income (as a Paramedic, mind you) as the others have already stated.
The schools that teach it will fill your head with stories of glory and demand as they cash your check. You are then stuck with another certification that truly does not make you in more demand, especially at the basic level, whereas you could of put that money towards medic school.
One route is to maintain your basic, go to the police academy, get hired, complete probation (typically 1 year), start applying for specialty teams, get chosen and qualified, convince them to pay for your medic school or convince them as a basic you can assist them, and complete it all that route.
Another route is come overseas, but again that is a little more tactical than most wish to subject themselves to. As for that route, you need many years experience and medic as well, so if you start now I am sure you can do it.
I do not believe anyone here is being mean or trying to kill your dream. The role may evolve more over the next few years, who knows, but at this time we are being realistic. There are very, very few jobs for a FULL TIME "tactical" PARAMEDIC in the states.
Good luck in your search and the pursuit of your goals.
