Sam Hanna is a former Navy SEAL-turned-NCIS Special Agent who is assigned to the Office of Special Projects in Los Angeles.
Born on January 14, 1972 to a father named Hanna who became a Colonel in the United States Marine Corps and an unnamed mother, young Sam harbored the dream of being a Navy SEAL from a very early age.
As a child, Sam was sent to school by his father who was a Colonel with his father disciplining young Sam very hard.
During his time in high school, Sam was a wide receiver on his high school football team.
After graduating from high school, Sam later joined the United States Navy, greatly disappointing his father who had hoped that his son would follow in his footsteps and become a Marine instead.
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 were both captured and tortured before being buried alive. Tragically, 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 (2010) with the two training together and during that time, Steve promised Sam a steak dinner.
In the early 2000s, Sam was called to Sudan and along with some SEALs, helped free a group of aid workers under attack from the Janjaweed. Sam killed one in self-defense who also happened to be the father of Mowadh Dusa. Feeling guilty over his involvement, Sam brought Moe to the United States.
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 which presumably occurred after he completed his training at FLETC.
During that time, he also met Michelle while working on a joint task force with the CIA with the two later marrying and having two children together, a boy named Aiden and a girl named Kamran.
