Price agrees to aid the 141, but insists that the war in America needs to end. He leads the 141 to raid a Russian port and gain control of a ballistic missile submarine. Once inside the vessel, Price launches a ballistic missile towards Washington, D.C. and sets its nuclear warhead to detonate in the upper atmosphere. The resulting EMP disables all electronic devices across the eastern seaboard, leaving Russian and American forces without logistics, tanks or air support, but giving the Americans a much needed advantage.[25] U.S. National Command Authority stationed in Cheyenne Mountain Operations Center sends the U.S. Air Force to bomb Russian-occupied strategic structures (including the White House) across Washington D.C. but the strikes are aborted, when green flares are lit on top of these structures, showing that the Americans have recaptured them and that the city remains in American hands.[22]
