Born on January 14, 1972 in New York City to Raymond Hanna who became a Colonel in the United States Marine Corps and an unnamed mother. Sam grew up in New York and 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 and had plans to go pro but a shin injury prevented this.

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 learned to swim after realizing he needed to be proficient. Sam would rise to the rank of Senior Chief Petty Officer in DEVGRU (SEAL Team Six) and his reputation made him be regarded as a legend by his fellows. He 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 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 active duty with the rank of Navy Senior Chief Petty Officer, joining the Revisits in 2002, having served the Navy for twenty years.

After retiring from the Navy in the early2000s, Sam spent some time at the VA hospital with the staff there helping him get his life together.

Once he was better, he 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.

Upon becoming an NCIS Special Agent, Sam was first partnered with fellow agent Mark Ruiz with their partnership lasting for a year before Ruiz later left NCIS due to him suffering from a problem with drugs.

According to Henrietta Lange in Bounty, G. Callen and Sam didn't trust each other properly until New Years Day in 2007. At that point they had been partners for less than a month, and it wasn't going well. Callen went undercover to meet an Armenian mob boss and Sam was assigned as his backup. Sam was caught by a sentry and the mob boss handed Callen a gun and demanded Callen shoot Sam as proof of loyalty. Callen aimed and fired his gun right at Sam's head because he knew the gun was empty due to its weight.
