Reedy Creek and the paramedics

I found out this weekend how strong the presence of Reedy Creek Improvement District's (RCID) emergency personnel at the Disney parks is. Seems they keep one team at DAK and one team at MGM all the time. And they keep two teams at Epcot and MK at all times. While they are themselves EMTs and paramedics, they don't keep ambulances around. They'd call for a real ambulance if they need one. But they do have a cart they can push out into the park. Not a "crash cart" (to revive a dying person) but something to maintain minimal life support, akin to some of the tools around on the ambulance itself.
