From Sean Black's chat There have been some insane detonations over Germany. Also there have been declass digs by the Stasi someone dug up from the 60s. In it are details about the entire subsurface bunker/tunnel network in West Germany??, specifically mentioning Bad Neuenahr (flood region), Marienthal (flood region bunker that was sealed off by military after the floods), Mechernich (NATO ammo bunker Europe) and all sorts.

We have seen MASSIVE flight operations there for MONTHS. This is a great "combat indicator" and not a coinkidinks
