the long version

"While at Purdue University on an NROTC scholarship in 1971, Roland Haas was recruited to become a deep cover CIA operative. He underwent intensive training to prepare for insertion into hostile areas, including High Altitude Low Opening (HALO) parachuting and weapons instruction. In the course of his first mission, which spanned Turkey, Iran, Afghanistan, and the former Soviet East Bloc, he assassinated several international drug dealers. In the middle of his mission Haas was thrown into an Iranian prison, where he was physically and psychologically tortured. Over the next thirty years he served the agency on an as-needed basis, engaging in such activities as hunting down and eliminating members of the Red Army Faction and extracting Soviet Spetsnaz officers from East Germany. Oftentimes in charge of finding his own cover, Haas decided to partner with an acquaintance and start an Oakland health club. This credible job brought him into close contact with steroid abuse in professional athletics, drug abuse in general, and the Hell's Angels, whom he believes tried to have him killed. Because of the attempt on his life, he moved to Germany in the early 1980s and served as site commander for the Treaty on Conventional Forces Europe (CFE). His most recent cover was as the deputy director of intelligence in the U.S. Army Reserve Command, which involved him with the Guantanamo detention facility."--Book jacket.
