When I first read

One of Public Affairs' primary responsibilities is to ensure factual reporting of events to the public and to counter enemy propaganda.

I thought I as a member of the domestic target audience was being strategically communicated with and assured that somebody is indeed conducting counterpropaganda, which has been a pet peeve and perpetual blog topic of mine for some time.  It was always my understanding that Psychological Operations conducted tactical and operational counterprop within an operational area and Other Government Agencies were supposed to perform the counterprop mission and attempt to mitigate some of the damage enemy propaganda does to the will and morale of the American people (domestic TA).  IMO, OGA's have not covered themselves with glory on that, giving rise to civilian irregular virtual militias and People's Information Support Teams in the Counter Insurgent Supportive blogosphere. 

Communication of operational matters to internal and external audiences is just one part of PA’s function. In performing duties as one of the primary spokesmen, the PA officer’s interaction with the IO staff enables PA activities to be integrated, coordinated, and deconflicted with IO. While intents differ, PA and IO ultimately support the dissemination of information, themes, and messages adapted to their audiences. PA contributes to the achievement of military objectives, for instance, by countering adversary misinformation and disinformation through the publication of accurate information.

I hope the young journalist at Bagram who slipped that new PA mission into the first sentence of the story doesn't lose too much of his fourth point of contact over it.
