|History: A combat veteran of over a hundred silent wars, Sam Fisher is one of the most experienced and highly-respected covert operatives in the N.R.I community. Prior to joining the N.R.I, Katarn had an extensive service career, working as a member of the NRI's Special Activities Division (Special Operations Group) and as a highly decorated soldier in the Spec Force, in which he served as an operator in both Spec Team 3 and DEVGRU, where he rose to the rank of Lieutenant Commander. He retired from active duty sometime later, but later returned to work for the NRI in 17 ABY, when he was recruited into N.R.I Spec Ops 5th regiment. Katarn is an expert in the art of stealth, trained in various techniques and tactics. He is extremely proficient in both armed and unarmed combat, specifically Specforce CQB and Krav Maga, and can also speak a wide variety of alien languages. When possible, katarn operates almost exclusively at night and prefers to work alone in the field. The rest of the information is being released slowly.
