The International Creature Elimination Force/International Creature Elimination League, more commonly known as I.C.E.F./I.C.E.L. was a special faction during the Rebirth era. The I.C.E.F. was founded in 1973, after the zombie apocalypse caused by the Soviets, by America, Britian, and Germany. The purpose of I.C.E.F., as its name suggests, is to eliminate any creature affiliated with zombies. The I.C.E.F. was comprised of soldiers/agents from the CIA's Special Activities Division, the Studies and Observations Group, Delta Force, Black Ops, and the US Marine Corps and Army.
