According to Mochel the documents illustrate a robust clandestine NSA operation within the Austrian capital.
Mochel reports there are currently three major NSA stations in Vienna.
The first one in the US Embassy of Viennas 9th district.
The third station called the NSA Villa location in Potzleinsdorf.
The core of the operational processing takes place in the second IZD tower.
Air-conditioning plants has been recently added to the tower suggesting that additional computers were likely installed.
Erich Mochel has done a good job sorting through Snowdens leaked documents to sort this out.
The NSA is doing what the NSA does spy on as much as they can.
Making this a very fertile pruning ground for spy activity.
