Little background if you don't know. This is a document from the Congressional Research Service, CRS dealing with the Ruskie "Special Operation" in Ukraine. These are the people who supply "official" information to Congress and anybody else who wants to download. Can be VERY interesting sometimes from the historical as well as political stand point!
CIA has a similar site dealing with intel Haven't surfed around there for a very good while. Not sure of the link. If interested, reply and I'll see if I can find it.
Both sites are filled with "governmentese"!
