The After Burner in the Fbi?

In the secret service, you had to work between eight and ten years in a field office if you wanted to go to the president's detail by then. Even mediocre agents worked a minimum, probably five to ten reasonably good sized cases. What the hell do you learn in two to three years to be managing cases like yours out in the world? The question is this, are these people that are unbelievable intellects that just grasp the process ind their savants exactly right? Or the people that understand that you've got to check the box, and then you can move on and get the next pay grade?
