Signal intelligence is the most secret, and most misunderstood, weapon in the modern espionage arsenal. As a reliable source of information, it is unequaled, which is why Government Communications Headquarters, almost universally known as GCHQ, is several times larger than the two smaller, but more familiar, organizations, MI5 and MI6. Because of its extreme sensitivity, and the ease with which its methods can be compromised, GCHQ’s activities remain cloaked in secrecy.
