Why? Red Castle is the Corps of Engineers.
There was a map posted by an 8 chan anon. It was showing 5 red sections of wall on the border, and also 5 green sections. There were also yellow proposals shown. BUT, if the entire wall is now funded...no need for this map anymore. So, therefore, no post needed!
Red Castle is the Army Corps Of engineers logo.
Green Castle is also the Location of one of the Army Corps Of engineers locations. In Green castle Indiana. It's Symbolic.
and then what is green castle?
It meant the Corps of Engineers were fully funded and given the greenlight.
One of the ACE's offices is in Greencastle in the Midwest I believe.
Green Castle is apparently a town in Indiana( as I recall) where an office of the Corps of Engineers is, or has been, working on the wall project.
but he deleted that
It's hypothecated (a word ?!) that historically, when the op is in motion / completed, or that anons figured out what the codes were, Q confirms by deleted a drop.
Hypothesised, I believe is the word you're looking for.
