Setting: Right in the middle of World War 3. (c. early 1963) The Cuban Missile Crisis has turned the Cold War hot. The war is simultaneously nuclear and conventional on multiple fronts. Soviet Navy troopships assist in the ground battle in Europe. Detecting an incoming NATO bomber strike, the troopships retreat into the Atlantic. Moscow is nuked, and the troopships lose contact with HQ in the middle of the ocean. Running low on food and supplies, the troopships turn directly toward the US east coast (they would have gone to Iceland/Greenland/Canada, but there was a strong naval presence there and the Soviet ships were not armed for a head-on fight). The Soviets have already nuked Washington DC. They tried to hit the CIA as well, but missed Langley completely and hit nearby Reston. The CIA building is partially destroyed, but most of the documents and files inside remain intact. An infantry group is tasked to secure the area and destroy any potentially important artifacts of the former CIA - before the Soviet troops land and find something important. (They then must take up position to defend against the impromptu invasion) Here, one of my characters finds a document about a [FICTIONAL] tunnel system underneath Manhattan, NYC. The tunnel, presumably 19th-century Freemason in origin, was commandeered by the Department of Defense in the early Cold War. The document details a project to reinforce and cement the tunnels, nuclear harden them, and convert them to a subterranean fallout shelter-military base combo. An attached memo, however, states that the project was abandoned in 1951 due to the outbreak of the Korean War and its completion status is unknown. One question, though - the surrounding area has already been nuked at least twice. All the people are dead or have left. I need my character to find this document, as it is relevant to the plot (after the war), but speaking from a realistic, strategic, and logistical point of view, wouldn't it make more sense for the USAF to nuke Langley themselves? Can anyone come up with an explanation why they might not? Or, possibly, an alternate location this document may be?
