According to JP 1-02,United States Department of Defense Dictionary of Military and Associated Terms, a military journalist is "A US Service member or Department of Defense civilian employee providing photographic, print, radio, or television command information for military internal audiences. See also command information. (JP 3-61)"
Military journalists are part Public Affairs, defined by JP 1-02 as "Those public information, command information, and community relations activities directed toward both the external and internal publics with interest in the Department of Defense."
Command information, therefore, is just one of the responsibilities of Public Affairs set by Department of Defense policy. DoDD 5122.5 sets forth these Principles of Information:
E2.1. INFORMATION It is DoD policy to make available timely and accurate information so that the public, the Congress, and the news media may assess and understand the facts about national security and defense strategy. Requests for information from organizations and private citizens shall be answered quickly.
In carrying out that DoD policy, the following principles of information shall apply:
E2.1.1. Information shall be made fully and readily available, consistent with statutory requirements, unless its release is precluded by national security constraints or valid statutory mandates or exceptions. The "Freedom of Information Act" will be supported in both letter and spirit.
E2.1.2. A free flow of general and military information shall be made available, without censorship or propaganda, to the men and women of the Armed Forces and their dependents.
E2.1.3. Information will not be classified or otherwise withheld to protect the Government from criticism or embarrassment.
E2.1.4. Information shall be withheld when disclosure would adversely affect national security, threaten the safety or privacy of U.S. Government personnel or their families, violate the privacy of the citizens of the United States, or be contrary to law.
E2.1.5. The Department of Defense's obligation to provide the public with information on DoD major programs may require detailed Public Affairs (PA) planning and coordination in the Department of Defense and with the other Government Agencies. Such activity is to expedite the flow of information to the public; propaganda has no place in DoD public affairs programs. DODD 5122.5, Sep. 27, 2000
JP 1-02 defines propaganda as "Any form of communication in support of national objectives designed to influence the opinions, emotions, attitudes, or behavior of any group in order to benefit the sponsor, either directly or indirectly."
The effort to counter enemy propaganda, therefore, both directly and indirectly benefits the sponsor. It has been a function of Psychological Operations (PSYOP) and not Public Affairs. JP 1-02 defines Counterpropaganda Operations as "Those psychological operations (PSYOP) activities that identify adversary propaganda, contribute to situational awareness, and serve to expose adversary attempts to influence friendly populations and military forces. (JP 3-53)"
