John Doggett
Biography

From "The X-Files" Official Site:
Agent John Doggett joined the FBI from the New York City Police Department, where he served as a Detective in the Fugitive Division's Warrant section. Approaching all of his investigations like a doubting cop, he believes that everything can be explained with standard police techniques. So it is no surprise that after only five years at the Bureau, he is assigned by Deputy Director Kersh to run the task force looking for Mulder. Although he may be set up to fail, Doggett has resigned himself to solve the case.

Masters and doctoral degrees in Public Administration from Syracuse University prove Doggett's willingness to conform to the government's blueprint. He is the consummate insider on the fast track to success. Previous to his police work, Doggett held the rank of Sergeant in the United States Marine Corps' Amphibious Unit and played a role in the Multi-National Peacekeeping Force for Lebanon Development. With six years in the military, he retired with commendations after being wounded in the line of duty.
