In 2036, a civil war between pro-Russian insurgents and local resistances in Ukraine leads the US to deploy peacekeeping forces. During an operation, a team of United States Marines and "Gumps" (robotic soldiers) are ambushed. Disobeying an order, drone pilot 1st Lt. Harp deploys a Hellfire missile in a drone strike against a suspected enemy launcher, killing two Marines but saving 38. As punishment, Harp is sent to Camp Nathaniel, the US base of operations in Ukraine where he is assigned to Captain Leo, a highly advanced and experimental android super-soldier masquerading as a human officer.
