In addition to security and law enforcement implications, it doesn't take much of a stretch of the imagination to come to the conclusion that war gaming these scenarios takes into account continuity of government directives, which means that elite members of reserve government elements need a place to go if the SHTF.
The fact that bunkers exist is no secret, and as was pointed out in the aforementioned articles, there are many of them around the country. Rumor has it that the government has built literal underground cities spanning hundreds of thousands of square feet, complete with everything from nuclear power generation to facilities capable of manufacturing just about any modern day product. The idea is that in the event of a global cataclysm, the human race would be able to survive and thrive, without losing the technological advancements achieved over the last couple of centuries.
