How did John Clark come to lead RAINBOW?
Rainbow Six takes place in a world created by Tom Clancy that centers around Jack Ryan, the protagonist in the majority of his novels. For more information on this so-called “Ryanverse,” check out the Tom Clancy FAQ. Although the creation of Team RAINBOW is not detailed in the game, the novel explains that John Clark wrote a memo to top figures in the U.S. administration that identified the need for an ultra-elite multinational counter-terrorist unit to combat international terrorism in the post-Cold War world. He got the go-ahead to set up this “blackest of black-ops” project that very few top officials in the world know about.
