The team is lead by Leroy Jethro Gibbs, a Special Agent; his skilled investigating instincts have made him a smart and tough interrogator as well. Bending any set rules depends on how desperate he is on his case and Special Agent Tony DiNozzo thus makes a perfect assistant to him. DiNozzo was a homicide detective formerly and his street-instincts are a big help to Leroy.
The duo is joined by a dark witted and Gothic Abby Sciuto (forensics specialist) and Dr. Donald “Ducky” Mallard (a medical examiner) besides special agent Tim McGee, a real fleet-fingered operator on the computers. Others joining the team are special agent Caitlin “Kate” Todd (former USSS agent), Mossad Agent Ziva David (who replaces Kate) and a new director, Jenny Shepard, who loses her post to Leon Vance later.
