Sam Hanna is a former Navy SEAL-turned-NCIS Special Agent who currently works for the Office of Special Projects in Los Angeles and who also serves as fellow NCIS Special Agent G. Callen's partner in the field.
Born to an unnamed mother and father in Brooklyn, New York, Sam's dream from a very early age was to be a Navy SEAL.
As a child he was sent to military school by his father Colonel Hanna who served in the marines. He disciplined Sam very hard and was rather disappointed when Sam joined the navy instead the marine corps.
After finishing high school, Sam presumably enlisted in the Navy and finally achieved his dream of becoming a SEAL. During his time as a SEAL, Sam served in Bosnia, Afghanistan, and Iraq. While on one mission in Bosnia, Sam, along with another member of his unit, Dickerson, was captured and tortured before being buried alive.
Dickerson, who had been shot, later succumbed to his wounds and died while Sam was eventually rescued by the other members of their team.
At some point, Sam met and befriended Lieutenant Commander Steve McGarrett with Steve promising a steak dinner.
Sam eventually left the military with the rank of Senior Chief Petty Officer and applied to join NCIS, which resulted in him being assigned to the Office of Special Projects in Los Angeles.

Like the other members of the OSP team, Sam made his debut appearance during the Season 6/backdoor pilot episode, Episode:Legend (Part 1).
Sam was also present when Callen was left gravely wounded in a drive-by shooting during Episode:Legend (Part 2), and after shooting at the assassins who later fled, arrived on the scene, and tended to Callen while also calling for an ambulance, urging Callen to stay with him.
