What Can You Do? : OPSEC

There are many countries and organizations that would like to harm Americans and degrade U.S. influence in the world. It is possible and not unprecedented for spouses and family members of U.S. military personnel to be targeted for intelligence collection. This is true in the United States and especially true overseas! What can you do?

1. Be alert
Foreign governments and organizations can collect significant amounts of useful information by using spies. A foreign agent may use a variety of approaches to befriend someone and get sensitive information. This sensitive information can be critical to the success of a terrorist or spy, and consequently deadly to Americans.

2. Be careful
There may be times when your spouse cannot talk about the specifics of his or her job. It is very important to conceal and protect certain information such as flight schedules, ship movements, temporary duty locations and installation activities, just to name a few. Something as simple as a phone discussion concerning where your spouse is going on temporary duty or deploying to can be very useful to U.S. adversaries.

3. Protecting critical information
Even though this information may not be secret, it is what the Department of Defense calls "critical information." Critical information deals with specific facts about military intentions, capabilities, operations or activities. If an adversary knew this detailed information, U.S. mission accomplishment and personnel safety could be jeopardized. It must be protected to ensure an adversary doesn't gain a significant advantage. By being a member of the military family, you will often know some bits of critical information. Do not discuss them outside of your immediate family and especially not over the telephone.
