SIOP anyone here exposed to it?

When I was assigned to SAC I was exposed to it daily. We had to know where to send the b52's, ICBM, sLICBM if the SHTF. I think we went from 50.000 targets to around 2k after Russia folded. Not sure since I am now out of the loop. Can you imagine 50,000 warheads flying thru the air!! And that is just from our side!! Tom
