name of Adamska is derived from "Adam."[34] Both alluded to Ocelot's American origins, with "ADAM" being the codename of the NSA defector assigned to meet Naked Snake during Operation Snake Eater. The name "Adam" derives from the Hebrew noun ha adamah meaning "the ground" or "earth," and is the name of the first man in the Book of Genesis from the Hebrew Bible and the Christian Old Testament.

Ocelot's nickname of Shalashaska (gained from the Mujahideen he tortured during the Soviet Invasion of Afghanistan) was derived from the mispronunciation of a portmanteau of the words "Sharaska" - a slang term for a suspicious, hastily thrown together organization which was also applied to secret R&D facilities in Soviet labor camps and "Shaska" - a type of saber from the Caucasus,for his legendary bravery and fighting ability (in tribute to Fyodor Arturovich Keller). When put together they create the word "Sharashaska" which then became Shalashaska.

During the Shadow Moses Incident and the Big Shell Incident, Vulcan Raven and Vamp referred to Revolver Ocelot as "General Ivan" and "Crazy Ivan,"[35] respectively.[36] Ivan, the Slavic variant of the name "John," is also a slang term for Russian people in general.
