I believe that CASTLE_ROCK could be a place holder for the pentagon. We have all seen Q Drop 4414, and the CASTLE_ROCK at the end of it Q Drop 4413 Is not spoken about too much though. It holds two links, one to axios, speaking about Pentagon officials resigning, and another talking of upper level military officials going against Trump. It also speaks about "Those Loyal" to country values and the Oath taken. The good people who serve proudly for America CASTLE_ROCK Q Drop 3782 which shows Trump standing behind 2 marines, and states "Castle clean". The last one I will link is to Q Drop 4433 Which is an image of an American Flag, File name CASTLE_ROCK_GODSPEED.png The ONLY references to CASTLE_ROCK are DC Military Brass related. Castle has been used in the past to describe other parts of the military, but I believe that _ROCK is describing the Pentagon. I don't think its related to Colorado. There is nothing notable related to that town and Q posts... One guy mentioned something about a star from WW2 but that doesn't tie in with Pentagon officials resigning. Yes Cheyanne Mt. and other mountain complex' but things with a strong title usually get shortened to other titles with Q.
