A little on buried tanks...

I wish we'd known about this years ago, when I was a student at OSU, one of the miniatures club's "experts"* had us attack one or another of the Norwegian airfields in a WW3 scenario at least twice. Hidden PzIIIs in the hills would have been just the kind of wrinkle we would have loved.
*Minis club experts (my definition): back then, most of us were students, with a handful of alumni. The latter were the guys who had money to buy & paint minis, so they were the sources of scenarios, referees, and so on. We had one guy who had WW2 tanks, another with WW3/Vietnam stuff, and so on for Am. Civil War, WW2 ships, WW2 planes, and Napoleonics. They worked out a schedule at the begining of every quarter; the rest of us just showed up and played, never bothered to read the rules.
