Go, George!
FYI All:
"smell-um" were one a those strange outcomes of the post-Potsdam division of Germany into 4 zones... Each "allied power" (US, UK, FR, USSR) was allowed to field an official "legal" military observer team in the other guy's zones. The team was uniformed and allowed to carry small-arms...
Think "legal spies". The mission was to look at what the other guy was doing in "his" sector... Natch, each power immediately designated various areas within their zones as being "off-limits" or "restricted" - meaning the -LM teams were not allowed to go in there and observe.
Of course, these were the ONLY places anyone actually wanted to look in!
Hence, the "SMLM hunt". The Sovs would try to sneak in and take pics of military bases and activities- and scuttle back into their authorized access areas before we could catch them. The rules were that the SMLM had full freedom and diplomatic immunity- in their authorized access areas- but if we could catch them "inflagrante" within the security or restricted zones, well...
The game was played with suped-up Benz cars and big telephoto rigs on their side, and helicopters with nite-sights and other stuff on our side.
And the chase was FUN! Think about trying to "touch-n-go" on a speeding Mercedes 600 on a country lane in the dark...
