U.S. Army, "Information Operation" (U.S. Army Field Manual 100-6) (Aug. 1996).

Overview
This manual makes an attempt to clarify the confusion surrounding information operations caused by the many and varied terms and their sometimes inconsistent definitions. This manual remains in force as the current Army doctrinal manual on the subject.

FM 100-6 identifies activities that support information operations as acquiring, using, protecting, managing, exploiting and denying information and information systems. This new doctrine acknowledges the tremendous growth in information, information systems and information sources and recognizes the implications of the information age.
