When I was stationed in Thailand, I spent most of my time at the 7th RRFS (7th Radio Research Field Station). The name of the unit was a cover for what we were doing ... but I guess it was some sort of feeble explanation for the humongous antenna we had there. Anyway, our shoulder patch (Ramasun Station) was a big #7 with a cobra and a lightning bolt. I chunked all of mine in the trash years ago. Dangit! This one (in pretty sad condition actually) just sold last month on The Bay for $100. Crap! I'm a frigging bozo!
