Leroy Jethro Gibbs



Special Agent Leroy Jethro Gibbs is a retired Marine sniper and now head of the Naval Criminal Investigaton Service's (NCIS) Major Case Response Team stationed at the Washington Navy Yard in Washington, D.C.

Gibbs has worked at NCIS for nearly two decades. He joined NCIS (then the NIS) in 1992 as a Junior Agent. He was typically referred to by his boss, Mike Franks, as "Probie" or "Gunny", a reference to his military rank of Gunnery Sergeant, something that continues to this day. Gibbs rose through the ranks until he was put in charge of the Major Case Response Team. He is often referred to as "Boss" or other humorous variations thereof by the members of his team.

Gibbs serves as the main protagonist of the television show NCIS (formerly Navy NCIS) and is portrayed by Mark Harmon, who has been nominate twice for the People's Choice Awards for this role.
