Most of them don't get anywhere near the jumps that most civilian jumpers get. My dad's a PJ and has around 1,200 freefall and a few static line rounds (in a 30yr career). I'm a SERE Specialist and have about 30 jumps on rounds, still waiting to go to military free fall school...hopefully. The jump teams that have been mentioned here aren't an actual job, but rather a special duty, so all those people are qualified in something else as well, which they will probably go back to after a certain number of years with the team. Other special duties that get to jump a lot would be MFF instructor, or Test Parachutist.
