Fred Judge joined the British Army at the age of 15 in 1954, serving with tank and missile-transporting units in Germany and South Arabia until he transferred to the Intelligence Corps in 1968. At the height of the Cold War, he was posted to the intelligence section of a brigade headquarters and then to a security company.

Because he spoke fluent German and had a good knowledge of Polish, his work involved interviewing civilian employees in the British Army who travelled to Communist countries, to find out if a Communist intelligence agency had recruited them as spies.

In 1984 he joined the British Services Security Organisation (Germany) which acted as a communications channel between British Forces Germany and the security services: MI5 and MI6 in Britain, as well as other European intelligence agencies.

Fred Judge retired in 1999, and now records the official history of the Intelligence Corps for its museum and archives.
