Rainbow Six
Tom Clancy
 Central Intelligence Agency operatives John Clark and Domingo Chavez join Special Air Service (SAS) officer Alistair Stanley in forming an elite multinational counter-terrorist unit known as Rainbow, based in Hereford, England. The unit consists of a highly effective and cohesive pair of operational squads, supplemented by intelligence and technological experts from the SAS. Clark is the commanding officer, while Chavez leads one of the two squads. Not long after the establishment of Rainbow, a bank in Bern, Switzerland, becomes the site of a hostage situation, eventually determined to be led by wanted terrorist Ernst Model. In an early and desperate show of resolve, the terrorists kill one of the hostages, leading the Swiss government to seek help from Rainbow. Chavez's Team-2 is deployed to the scene and, disguised as policemen, is able to successfully breach the bank and kill the terrorists with no further loss of civilian lives. Several weeks later, Chavez is deployed to Austria, where a group of left-wing German terrorists have taken over the schloss of a wealthy Austrian businessman, Erwin Ostermann, in order to obtain imaginary "special access codes" to the international trading markets. Through careful planning and negotiating, the terrorists are persuaded to take their hostages out to a waiting helicopter, presumably to make their getaway. On their way to the helicopter, Rainbow's disguised shooters ambush and kill them. Soon afterward, even more terrorists take over a Spanish theme park, demanding the release of Carlos the Jackal in exchange for the thirty-five children they have taken hostage. Due to the size and scope of the operation, Rainbow deploys both of its squads. During the stand-off, Rainbow is unable to prevent the terrorists' execution of a terminally ill Dutch girl. The squads manage to eliminate the terrorists without further loss of innocent life. Clark and his colleagues become suspicious about this flurry of activity from older terrorists. Unbeknownst to them, radical eco-terrorists from a biotechnology firm called the Horizon Corporation have orchestrated the previous attacks, having hired ex-KGB officer Dimitriy Popov to foment the incidents. The increase in terror attacks helps their security firm land a contract during the Olympic Games in Sydney, Australia. From within the Olympic security apparatus, they plan to launch a sophisticated bioweapon attack intended to wipe out the majority of the human race. Upon learning about Rainbow, Popov directs members of the Provisional Irish Republican Army to take over a local hospital in Hereford near Rainbow's base, take Clark and Chavez's wives hostage, and ambush one of Rainbow's squads. Rainbow and the SAS retake the hospital, capturing some of the terrorists. Interrogation reveals Popov's involvement in instigating the attack. Now the focus of a manhunt, Popov is kept hidden at Horizon's secret base in Kansas. Upon learning about the planned Olympic attack, an appalled Popov escapes the compound and contacts Clark. Fortunately, Chavez is present at the Olympics as a security consultant and manages to thwart the attack. Their plans destroyed, the eco-terrorists retreat to their refuge deep in the Brazilian rain forest, hoping to negotiate a deal to return to the United States. Clark, knowing that they may never be put on trial, tracks down the Brazilian hideout and deploys Rainbow to the location. After Rainbow defeats the eco-terrorists' militia force and destroys their facility and supplies, Clark has the survivors stripped naked and left to die, taunting them to "reconnect with nature." For his critical assistance, Popov is not charged for his role in the attacks. The Horizon Corporation continues as a legitimate pharmaceutical corporation, without their CEO and the other employees involved in the never-revealed plot.
