If you were responding to my post, it was during WW II. The "duck and cover" Cold War stuff was about a decade later. In my case, my military service was during the so-called Cold War. The Cold War was a misnomer, it was never cold. Personal for me, as I was close to situations where US personnel were killed by the Soviets. 'Nuff said.
For those living on the coasts during WW II, air raids, sub attacks, and landing of spies and saboteurs were not unrealistic fears.
