What is the setting of Rainbow Six by Tom Clancy?

The setting for the majority of Rainbow's activities is their military headquarters, which provides a backdrop for their intensive training, official meetings, strategy sessions and personal living quarters and off-duty socializing. Located in the green hills of Hereford, England, the complex includes John Clark's large office and adjoining staff office including one for his assistants. Senior staff members such as Alistair Stanley and Bill Tawney and Rainbow team leaders Chavez and Covington all have private offices nearby.
