Information Operations is far from Psyops, sometimes they coincide, sometimes they conflict, but never one in the same. This has been one of the most frustrating things for me throughout my service, in one form or another.
Ron,

The Joint Definition of IO and everything I have seen in the past 8 years puts PSYOP as an operational component of IO.

Most folks assume right away that any discussion of IO is speaking to non-lethal operations. Some understand that IO can be kinetic in that it seeks to destroy information technology by various means. Most do not grasp that IO using PSYOP can be lethal, the Rwandan genocide offering a particularly stark example.
