US troops are training for underground combat.
But we already knew that because we watch the movies.
Hunger Games - Mockongjay part 2
The arena has moved underground
And of course, we learned in the Harry Potter books that the real treasure and power is Gringott's and is stored in underground caverns. There is a country on the planet that does not have a territory above ground, yet it is SOVEREIGN. The SMOM is not underneath Malta. More of it is in the mountains of Switzerland where the gnomes of Zurich live. But it is in other places as well, and the governments of the countries where these mountains are located, do not control the sovereign depths of tunnels and cities and CAVEs that are underground.
NO CAVE is safe for them. They will be trapped inside by a WALL or they will be routed by the underground infantry of the US military.
This whole plan is far bigger than you realize, and the entire set fo Star Trek series starting in the 1960s has been part of the whitehat movement to prepare the people for the truth. Did you see the last episode of Star Trek Discovery where an angelic being was introduced? Demons are a form of angelic beiong, even SATAN and LUCIFER are fallen angelic beings. So could the ETs that we have been waiting for actually be angels?
Did you see the last movie starring Patrick Stewart? The Kid who would be King. It is telling the offspring of the occult bloodlines that they are special, but they can also choose the way of good. Similar shows are Magicians or Marvel's Runaways
Whitehats have now infiltrated and taken control of much of Hollywood and this began even before Trump ever became a candidate. POTUS is at the top, so BOTTOM TO TOP also means that the Presidency of the USA was one of the LATER ACTIONS in this grand plan.
