Intercepted Transmission from Greenbrier, WV

As you know, I am a survivor living in Northern West Virginia. Greenbrier, a military bunker built during the Cold War, is not far from where I am holding out.

I turned on my CP radio this morning and recieved a strange and frantic brodcast from Greenbrier. Could this mean that the government is still intact? If they are, why do they refuse to help us survivors?

Here's the transcript of the transmission:

This is very disturbing. Who or what is Foxtrot 137? What is the location of the coordinates? Have the infected overrun Greenbrier? Post your thoughts in a comment.
