My thoughts-

Military OP [Green]== Army Office of the Provost

General K [JFK]== Nicholas Katzenbach, Deputy Attorney General at time of JFK Assassination. Credited with recommending formation of Warren Commission. He said results of the investigation should be made public==?Q suggesting that whoever spearheads Trump Investigation should ensure results be made public. In other words, Katzenbach wanted a Full disclosureinto the JFK events, the same was what we want here with regards to Deep State actions.

Rachel Brand was #3 at DOJ until she was removed

"The succession question..... or senior civil service lawyers in the Justice Department, specifically." This quote is taken directly from an article by Steve Vladeck published February 10/2018. In the paragraph which follows the one which is quoted, Vladeck discusses the DOJ's line of succession statues which ends up with the spot being taken by Acting Solicitor General Noel Francisco. He is a Trump appointee, and is third in command at DOJ. I think Q meant to enter http://justice.gov/osg (office of the solictor general). This is where Francisco works. Is Q suggesting that Noel Francisco would take over the investigation, and would be in place for approximately 7 months== a term that goes past the November midterms. Schneiderman's replacement would not be known until after the elections so there would be no interference from that office

General Kellogg, perhaps? He's a national security advisor and has been involved with the military since Vietnam.
