Who is revolver ocelot

Revolver Ocelot is a member of the fictional special forces unit called Foxhound from the Metal Gear Solid video games by Konami and Kojima productions. During the cold war he served as a Soviet Major but was secretly a double agent by the code name of Adam for America. Near the end of the cold war Ocelot (real name Adamska) began working more actively for America and after the end of the cold war he joined up with the current Fox unit commander Major Zero to work for his secret organization called "The Patriots". I would go into details on the patriots but that would take a really really long time so I recommend checking them out through the metal gear wiki or something like that. Anyways after secretly joining up with "The Patriots" he officially enlisted in the Foxhound special forces unit. During a training excercise (probably spelling fail) on the Shadow Moses island he was involved with a coupe against the U.S.A. along with the rest of the Foxhound unit but that was eventually defeated by former Foxhound commando Solid Snake. After the incident at Shadow Moses Ocelot dissapeared and reapearred right around 5 years later at the head of the ex-spetznaz Gurlukovich special forces unit and destroyed a marine tanker that was disguised as a civilian vehicle after stealing a prototype weapon from the tanker and vanished again. A few years later an offshore ocean purification rig was hijacked by terrorists and Ocelot was involved in that incedent as well. I'm being vague on these "incidents" because I don't want to spoil the plot for you if you haven't played the games yet or whatnot, but Ocelot is also involved in the 4th Metal Gear game but not as "Ocelot" self. Mind control is involved so I won't include his exploits from that one.
I hope this answer helps you out and hopefullly if you aren't into the Metal Gear series you'll check it out. They're definitely worth it ;D
