"US law and DOD policy prohibits DOD from using psychological operations (PSYOP) units to conduct operations against US citizens. However, these assets can be used to help disseminate critical information to the civilian population. DOD may use PSYOP personnel and equipment to support activities such as information dissemination, printing, reproduction, distribution, and broadcasting". (JCS/DoD, CBRNE CM (JP 3-41), 2006, p. viii)
