Sergeant First Class Hector Lucian Williams (United States Army, callsign: Hammerhead) was a fictional character on the CBS television series The Unit. He was portrayed by Canadian actor Demore Barnes.

Hector was a Unit operator assigned to Alpha Squadron of the 1st Special Forces Operational Detachment - Delta (1SFOD-D) (official cover as the "303rd Logistical Studies Group"). He was an experienced marksman, and frequently served as a sharpshooter for the team. According to his uniform, he had both Special Forces and Ranger special skill tabs. Williams was likely the most diverse member of Alpha Squadron. He served as one of the team's medics, and was possibly an SF medical sergeant prior to joining the Unit. He was also cross trained in breaching demolitions. He, along with Charles Grey, also served as an instructor in close quarters battle for a SWAT unit, and designed the deliberate assault plan for the Braydon School Takedown in the "In Loco Parentis" episode. He was fluent in Arabic and Spanish, as well as Papuan Tok Pisin, and could speak German, Portuguese and a Pashto/Urdu dialect. Hector's cover was that of a "logistics clerk".

In Season 1, Hector was engaged to the daughter of a retired paratrooper who looked upon Hector with disdain due to his career in "logistics." The paratrooper was familiar with Colonel Tom Ryan, and asked for Hector to be transferred to the 82nd Airborne Division. Ryan let the father know subtly that Hector was not in logistics, but actually a member of a counter-terrorist organization. The father's attitude toward Hector changed, which Hector's fiancée noticed. He came clean to her that he was an operator, and she, not seeing job security out of the Army in his future, ended the relationship.

In Season 3, Hector met a woman named Annie at a local bar. She was a waitress and former US Army medic who happened to know Tiffany. They went on a date and then shortly thereafter (with some encouragement from the other Unit women) met up at a local motel in a nearby town. While there, Hector discovered Tiffy and Colonel Ryan having an affair.

During the Season 3 episode "Five Brothers," Hector was killed when he was hit in the neck with a bullet fired by a sniper as the team made its escape from Hezbollah during the rescue mission in Beirut; the sniper's bullet ricocheted from a bone in Hector's neck into his chest whilst caring for injured team-mate Charles Grey. The irony of this is that during the episode, and also during the episode's promotional spots, the team member Charles, Hector's roommate, is speculated as being killed, but survives the ordeal due to Williams' medical efforts.

The cover for his death was that he was transporting documents across an airfield in Turkey when unexploded ordnance blew up, rolling his jeep and killing him instantly. This scenario is called "Play 16."
