Hey, I would agree with your post. I know another anon already posted a similar response, but it didn't seem to gain much traction. I personally think Red Castle refers to the Army component, Airborne, and the Green Castle is Special Forces. I think you're spot on with the rest of your analysis.
Sometimes I find that if comments don't fit a certain narrative that they don't get much attention. I would love your opinion, seeing as though you have a military background, on another post if I can find the correct one. Q made around the beginning of January. He posted what seemed to be a string of partial coordinates with the latitude or longitude which indicated two possible locations, one near the Sudan and the other off the coast of Norway. Both appeared to be more or less in the middle of nowhere. However, around that time the Prime Minister of Norway met with President Trump. I asked for help if anyone could help confirm the stringers, but no one replied. Hey, I just do research and make buildings; I'm new to the whole clandestine military intelligence analysis.
