NCIS is an American police procedural television series, revolving around a fictional team of special agents from the Naval Criminal Investigative Service , which investigates crimes involving the U. Navy and Marine Corps. The series was created by Donald P. He enlisted in the Marine Corps in and became a Scout Sniper.
He later travelled to Mexico and murdered the drug dealer responsible, a crime he kept concealed for twenty years. Since then, he has been married and divorced three times, and is single, although he has had a number of romantic relationships since his last divorce. Finding Ari later becomes an obsession for Gibbs after Ari shoots and kills original team member Kate Todd in front of Gibbs and DiNozzo in the season two finale, " Twilight ". Gibbs often shows frustration with his team particularly DiNozzo for rambling or McGee for getting sucked into technical rambling by slapping them over the back of the head, an action that is later shared between team members and known as a "headslap" or "Gibbs-slap".
He mostly suspended doing this however in season 14 and onward since DiNozzo left the agency, neither with McGee as the new senior field agent and DiNozzo successor nor with new agent Nick Torres, who often displays a variation of DiNozzo's behavior that "earned" him his headslaps previously.
Gibbs is often shown in his basement building boats, one of which he names after his daughter and another after one of his ex-wives. He is an expert sniper, as evidenced in " Hiatus " with flashbacks of him hitting a head shot at 1, yards of his family's murderer, who was driving a moving vehicle, and in " Jeopardy " when he hits a kidnapper with a very swift shot to the forehead taken with his left hand while kneeling inside a car trunk.
In " Truth or Consequences ", Gibbs saves his entire team by shooting the leader of a terrorist cell after DiNozzo and McGee get captured looking for Ziva. Gibbs has developed a fatherly relationship with most of his team members, especially Abby Sciuto.
