During the Cold War we had this Soviet KGB trawler shadowing us in the Sea of Japan for many weeks. The tiny spy trawler was a former rusty fishing boat being tossed around with high waves. Every time we tossed trash overboard, the trawler would sent a whaleboat to retrieve garbage bags to find anything information of value. Since we burn all classified materials, there was little value in trash.
One day the Skipper (An F-4 Aviator during the Vietnam War), call over the 1 MC and asked us to report back to the fantail with any old **** to get rid of. Some shipmates showed up with stacks of Playboys, Penthouse, Swank magazines. The intelligence officers glanced through them for any classified notes and placed them in a heavy duty plastic bag. The deck apes filled them up with air and sealed them up.
The signalman communicated with the Soviet boat to stand by for a special gift. Once we dumped it into the water, the Soviets pick it up opened it and started waving in excitement. Within an hour, our Skipper had a bottle Vodka and fresh Russian Bread.
