The lead guy is Leroy Jethro Gibbs, played by Mark Harmon - a no-nonsense leader who demands a top-notch performance from each of his team mates. Gibbs' boss is Leon Vance, who is played by Rocky Carroll. Leon provides overall direction for three different NCIS services. Gibbs' second in command is Tony DiNozzo, a younger version of Gibbs. Tony likes movies a lot and can drop quotes from some of the classics at a moment's notice. One of Tony's best friends and oldest team mates is Timothy McGee, who is played by Sean Murray. Tim is a computer geek who is able to hack into systems whenever necessary to save lives and advance the investigation. NCIS' medical examiner team is Donald "Ducky" Mallard, played by David McCallum, and his assistant Jimmy Palmer, played by Brian Dietzen. Abby Sciuto is the team's forensic scientist and moral support for the team. The newest member and final member of the team is Emily Wickersham, a woman who has amazing recall and can memorize a book.
