Dick Marcinko, founder of (Seal Team Six) officially known as DEVGRU. Author of Rogue Warrior

Summary: retired U.S. Navy SEAL commander and Vietnam War veteran. He was the first commanding officer of SEAL Team Six and Red Cell. After retiring from the United States Navy, he became an author, radio talk show host, military consultant, and motivational speaker. SEAL Team Six During the Iran hostage crisis in 1979, Marcinko was one of two Navy representatives for a Joint Chiefs of Staff task force known as the TAT (Terrorist Action Team). The purpose of the TAT was to develop a plan to free the American hostages held in Iran which culminated in Operation Eagle Claw. In the wake of the debacle, the Navy saw the need for a full-time dedicated counter-terrorist team and tasked Marcinko with its design and development. Red Cell Marcinko was the first commanding officer of this new unit. At the time, the Navy had only two SEAL teams. Marcinko purportedly named the unit SEAL Team Six in order to confuse other nations, specifically the Soviet Union, into believing that the United States had three other SEAL teams that they were unaware of. He personally selected the unit's members from across the U.S. Navy's special operations community, including a special counter-terrorist tactics section of SEAL Team Two, codenamed MOB-6. SEAL Team Six would be the Navy's premier counter-terrorist unit, like its Army counterpart Delta Force.[2][5] While typically a two-year command in the Navy at the time, Marcinko commanded SEAL Team Six for three years, from August 1980 to July 1983.[6]
