Kn.A.N.O.
kN.A.N.O is a militant group responsible for the theft of the Nano-Cell from an unnamed source.
Their appearance is only in Red Faction II and are seen at the start of the game in the chapter Foreign Lands that Alias and Shrike break into so as to retrieve the Cell for the Commonwealth.
Alongside some regular hired security, kN.A.N.O military units are seen sporting a Red beret style hat with a black brim, red shoulder and leg guards as well as waist protectors.
