Colonel Henry Jameson Duvall was an American sniper from 1st SFOD-D famous for his H-K firearms and F-S fighting knife. He worked for the 1st Airborn regiment or ACE also known as Task Force Green or Delta Force, who recruited him from Seal Team Six as a long-range scout sniper based on his high test scores. Duvall is the best of the best. He can shoot a dime from 2,500 meters away with pinpoint accuracy. He has Special Forces training and is an expert in a variety of weapons and skill tactics. He speaks 5 languages and has 2 medal of honors, and a legion of merit.

Originally, he was mistakenly reported as MIA, but is now currently listed as a POW in a followup review by ACE, and was correctly reported as being arrested for espionage and for treason by the Neo-Nazi Secret Soldiers or NNSS on account of Duvall's Germanic descent. NNSS is an internal terrorist organization responsible for the murder of 80,000 U.S. citizens, known for their xenophobic racism and state-of-the-art modern scientific human experiments, including up-to-date controversial torture methods and war crimes. Duvall is believed to have been captured by the NNSS and probably tortured to death, but without a body the POW case file remains open.
