Origin of OPSEC

There is nothing new about the principles underlying OPSEC. In fact, we can trace OPSEC practices back to the colonial days and the Revolutionary War. George Washington, our first president, was a known OPSEC practitioner. General Washington was quoted as saying, "Even minutiae should have a place in our collection, for things of a seemingly trifling nature, when enjoined with others of a more serious cast, may lead to valuable conclusion."

However, OPSEC, as a methodology, originated during the Vietnam conflict when a small group of individuals were assigned the mission of finding out how the enemy was obtaining advance information on certain combat operations in Southeast Asia. This team was established by the Commander-in-Chief, Pacific, and given the code name "PURPLE DRAGON."

It became apparent to the team that although traditional security and intelligence countermeasures programs existed, reliance solely upon them was insufficient to deny critical information to the enemy--especially information and indicators relating to intentions and capabilities. The group conceived and developed the methodology of analyzing U.S. operations from an adversarial viewpoint to find out how the information was obtained.

The team then recommended corrective actions to local commanders. They were successful in what they did, and to name what they had done, they coined the term "operations security."

OPSEC and Government Activities
Over the years it became increasingly apparent that OPSEC had uses in virtually every government program that needed to protect information to ensure program effectiveness. OPSEC professionals modified and improved techniques based on experience gained with many different organizations and in areas far afield from military combat operations.

Today, OPSEC is as equally applicable to an administrative or research and development activity as it is to a combat operation. If OPSEC is not integrated into sensitive and classified activities, chances are that our adversaries will acquire significant information about our capabilities and limitations.

It probably would have been difficult for the "Purple Dragon" team to foresee that, 30 some years later, the methodology they developed would become a national program.
