(U) The Day the Trigraphs Disappeared
FROM: the GRSOC Cryptologic History Program
Unknown
Run Date: 03/14/2005
As the Saddam Hussein regime collapsed, SIGINT collection ended (S//SI)
(C) On one of the most unusual days in US cryptologic history, the SIGINT trigraphs for an
entire country disappeared from collection tasking virtually overnight. The military and civil
infrastructures were gone; collection targets were obliterated with the stroke of a pen; SIGINT
reporting all but ceased. There was nothing left.
(S//SI) It was April 2003. The invasion of Iraq saw coalition forces streaming from southern Iraq
into Baghdad. The once-feared Republican Guards of the Saddam Hussein regime offered little
resistance. It was a time that everyone will remember.
(S//SI) "IQ was gone. Wow. I have worked this target from August 1990 through April 2003. To
me it was personal, like there's a void in my SIGINT life." Those were the thoughts of Mr. John
Whitelaw, Deputy Chief of Operations (D/J3) at the Gordon Regional Security Operations Center
(GRSOC). "But we have to turn toward planning for the future. What is ahead without Iraqi
military comms?" he mused.
(S//SI) On April 11, 2003 the DIRNSA issued an email, "With very few exceptions, the SIGINT
targets [of Iraq]... have ceased to exist. To use one measure, GRSOC issued just over 4,000
KLIEGLIGHTS* (K/Ls) during the last week in March; they've produced a little over 600 from 1-7
April." By the following week, reporting had dried up to a trickle.
(S//SI) May 1st became "an historic day in GRSOC collection history: IQA, IQT, IQZ, and IQM
were all removed from the routing tables in NIGHTGLOW" audio distribution switch, according to
an internal email by
a GRSOC system administrator. There were no more audio
cuts, no more transcripts, no more K/Ls, no more product reports. The targets were gone.
(S//SI)
, was serving as Chief of Operations (J3) at the GRSOC during
Operation Iraqi Freedom. When he read the message dissolving the Iraqi collection targets, his
reaction was dramatic, "Wow! Well, the world has changed. How does it affect the GRSOC? I
guess they'll be looking for a "peace dividend". Will we lose resources because of our success?
We are fighting budget cuts while still supporting our force protection missions. Now the
question is: how are the bad guys communicating? Now we have to develop a whole new target!
We might need more resources because we don't know what's out there."
(S//SI) He paused and began to reflect on the long-term effort that went into the Iraqi mission,
and the challenge that lay ahead. "It's really bittersweet. We did a great job and we won, but
now that means, in a political sense, that the threat, and the target, are gone. The new
challenge is - how do we provide force protection intel to our forces in Iraq who are being shot
at every day? We feel helpless because there are no comms to exploit to support them."
(C) Little did anyone know that almost two years later GRSOC linguists and analysts would still
be collecting on new targets in Iraq, but this time it is the insurgents.
*Notes:
(S//SI) Trigraphs = the three-character descriptors for collection targets that make up the
beginning of a case notation. In this case: IQA is Iraqi Air Force, IQT is Iraqi Civil Air, IQZ is
Iraqi Air Defense, and IQM is Iraqi Military (Ground Forces).
