Scott Helvenston, American soldier (b. 1965)
Stephen "Scott" Helvenston (June 21, 1965 – March 31, 2004) was a United States Navy SEAL. He was working as a security contractor for Blackwater Security when he was killed in the 31 March 2004 Fallujah ambush within days of arriving in Iraq.

Helvenston was a personal trainer for Hollywood celebrities such as Demi Moore (for G.I. Jane), and was also featured in the reality shows Combat Missions and Man vs. Beast (in the latter, he completed an obstacle course faster than a chimpanzee). He also starred in a reality series called Extreme Expeditions: Model Behavior months before he left for Iraq. The series was shot in Mexico and was finished, but never aired.

Helvenston's great-great-uncle was Secretary of War Elihu Root.He joined the Navy at 17 and became the youngest person to complete Navy SEAL training. He spent 12 years in the Navy SEALs until he left in 1994 as an E-6 (Quartermaster First Class).

Helvenston began training at Blackwater USA's facilities in March 2004, and developed a personal conflict with head trainer Justin "Shrek" McQuown. Helvenston arrived in Kuwait on March 18, where he was under the management of John and Kathy Potter, whom he knew from Combat Missions.
