(C) From its inception in 1966 and 1967, PURPLE DRAGON proved a major success at
improving the combat effectiveness of the units and operations it surveyed. PURPLE
DRAGON was so successful, in fact, that before the war was over the Joint Staff made
operations security programs, based on the PURPLE DRAGON model, mandatory for all U.S.
commands everywhere in the world. Operations security would prove so successful in the
end that President Ronald Reagan would make it a requirement for every U.S.
government department or agency, military and civilian, with a national security mission.
(U) It is the goal of this study to explore why and how operations security in general
and PURPLE DRAGON in particular came about. It will attempt, furthermore, to show how
the concept and methodology of OPSEC were developed; how OPSEC came to prove itself in
the rice paddies and jungles of Vietnam; how it came to win acceptance, first among the
U.S. military in Southeast Asia and the U.S. Pacific Command, then by the U.S. military
establishment worldwide; and, at last, how operations security came to become an official
policy of the United States government. Finally, it will seek to document the vital role
that the National Security Agency has played in the development of operations security,
from the birth ofOPSEC during the conflict in Vietnam to the present day.
