I also joined in 1979 and was in Kunsan during 1981. Our base fired live rounds at enemy ships weekly. Two airmen died under mysterious circumstances off base that year. Once, the Korean civilians asked us what the US was going to do. We asked them “about what?” Then they told us the NK just fired missiles at one of our SR-71s. They thought the US would cut and run away (of course we didn’t). One Captain was killed at Taegu that year from a building explosion (they leaked over 2 million gallons of JP-4 in 20 years and it finally blew and destroyed 5 buildings). While not technically a war zone, it certainly wasn’t a peace zone either.
