An update on the technical detail aspect of this story. CSTC-A does not maintain a PSYOP Cell. The unit in question (LTC Holmes), is a National Guard Information Operations (I/O) Cell. Fairly substantial difference between PYSOP and I/O.
The IO/public affairs relationship has been blurring. Add to that, many I/O officers are branched as another specialty, and thrown in the I/O position due to diminished need for that particular specialty in theater.
I'm not doubting the sunny side up briefings that are given to every visiting dignitary, but PYSOP it is not.
Danger Room has a pretty good summation of the known events.
h/t Mrs. Pigpen at Americas Debate for the link.
