told him that the OCT History Staff
s.
has no records or studies with the
names and identifying data for mem-
bers of CAT units in the Vietnam
War. I explained that if any such
records exist in CIA they would pro
ably be in DDO files, and told him
that I would ask DDO how he should
go about arranging for a search for
such data. I then called
DDO/IRO, who told me that Heddell
should send his request to DDO's
PCS. I reported advice to
Heddell, and the attached letter is
the result. I hope that PCS may be

Heddell) the DCI History Staff has

DIRECTOR
CO-2-79, 543
DATE: October 8, 1982
TO Deputy Director for Operations
Central Intelligence Agency
Attn: Chief
SUBJECT: Unknown, AKA CAT
During the past year, this Service has been investigating a
matter involving an unknown letter writer who has sent nu-
merous threatening letters to the President, Secret Service,
and FBI. The writer signs his letters, "CAT." Efforts to
identify this individual have thus far been unsuccessful.
It is believed that the letter writer maybe a Vietnam vet-
eran now receiving veterans benefits. As a result, liaison
has been established with the various components of the
Department of Defense. During this contact, the U.S. Army
advised that special units designated as Civic Action Teams
(CAT) were utilized in Vietnam from January 1.6, 1964 through
1972. These CAT units were predominately staffed by Special
Forces and U.S. Marine Corps personnel. Their function was
to provide medical assistance and advice to the Vietnamese
population for the purpose of preventing disease among U.S.
Forges. The U.S. Army advised that it was unable to retrieve
the rosters for CAT units, but that various sources exist which
might still possess such information, the CIA being one.
The U.S. Army recommended that this Service contact Kenneth
McDonald (Historical Files),CIA regarding MAC V -
Studies and Operations Group, in an effort to obtain names
and identifying data, if available, of personnel who were
serving on CAT units on March 11, 1965.
