Staff Officer's Guide
g. Accomplish your work during duty hours. Do not develop a habit of working late or on
weekends. While night or weekend work may be necessary at times, during peacetime those times
should be relatively few.
h. Accept responsibility for yourself. You are responsible for your own well being. Keep
yourself physically, mentally, and spiritually fit. Schedule your leave, hand off your actions, and go!
Spend time with your family. Provide a climate for your subordinates to do the same.
Operations Security
a. Operations security (OPSEC) is the process of selecting and executing measures that
eliminate or reduce to an acceptable level the vulnerabilities of friendly actions to adversary
exploitation. OPSEC includes the traditional functions of physical security, signal security,
information security, and countersurveillance.
b. The staff officer is exposed to highly classified information in an environment of urgency--a
combination that can cause a lapse of security. Safeguard classified material properly. Check
security clearances before giving someone classified information; do not assume everyone has the
proper clearance or the need to know the material.
c. Consider the telephone a security hazard. Never discuss classified information on an
unsecure telephone. Do not “double speak” around classified subjects. Be aware of classified
conversations in your area while using your telephone.
