I'd leave it to appear as it is. These days with the instant communications systems that there are, I'd move the commands elsewhere. Use it as a
terrorist magnet, kind of a big roach motel. Terrorsts check in but they don't check out! The majority of day to day operations are already handled
by the theater commands anyway. I'd be surprised if this isn't already the case. Put in some decent personel shelters and a couple of rapid
response teams to handle any attacks. The inner rings are actualy pretty safe.
