SIGINT During World War II
The NSA and GCHQ have jointly published a history of World War II SIGINT: “Secret Messengers: Disseminating SIGINT in the Second World War.” This is the story of the British SLUs (Special Liaison Units) and the American SSOs (Special Security Officers).

@ Bruce, All,
With regards,
In many ways it’s likely to be wrong 😉 Such was the need for security those involved were given “cover stories, whilst others invented their own ideas.
One official cover was as part of the “Paymasters” one invented was that their job was to distribute “The senior officers whisky ration”.
What is known is that lowly “Other Ranks”(OR’s) in effect “out ranked” even the most senior of officers.
Sadly the real “boots on the ground” stories are now in effect “nolonger known”. Because even with the publishing of the 1970’s F W Winterbotham book “The Utra Secret” those who had been in the SLU’s remained “The geese that delivered the golden eggs and never cackled”.
