Corporal Lee "Dash" Dashiel was a demolitions expert who helped Sgt. Nathan Hale and Pvt. Jimmy Sanchez find the only inhibitor which was crucial for the Sentinels' survival. Cpl. Dashiel first appears in St. Paul, Minnesota where the Chimera have taken over half of the city. An officer appears to him and tells him to report immediately to an installation in Keystone, South Dakota. Dashiel replies "Just a sec" and then presses down on a explosives plunger which in turn destroys a bridge killing and preventing the Chimera from crossing to the Army's position.
