Sam Hanna is a former U.S. Navy SEAL (retired with the rank of Senior Chief Petty Officer (E-8) from DEVGRU out of Dam Neck, VA) working as a Senior NCIS agent. He is the current partner and good friend of NCIS agent G. Callen .
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.

NCIS: Los Angeles Season 6Edit
Callen and Sam are trapped in and underwater submarine that is headed for a Marine Aircraft carrier. The sub has been made in to a torpedo and they are going to explode with the sub. They bust a hole in the sub to make their captors open the locked compartment they are trapped in. They then kill their captors and swim out of the sub. The Navy has blown up the sub just as Sam and Callen escaped. They blew it up because there were terrorists on the sub.
