On 56(F), our navigator of 'dusky appearance' wasn't
too keen on the recce feature of the Coontz-class destroyer, a large lattice work structure in front of the second funnel, being described as a 'coon cage'....
We were spared those interminable recce briefs about tanks and other Sovietski pongo machinery as an AD squadron. So no 'GT wheels' etc., thankfully.
One brave student once gave a recce brief about some Russki tank or other. Having introduced his subject, he put on a slide. Which was totally blank except for a little dot in the middle. "Here we have the T-** tank. This is the sight picture at the 1667 yard release range. You will notice the curved handrails, slack tracks, GT wheels and the position of the muzzle brake.......". Point made about stupid recce briefs for anyone except spies lurking in that famous upstairs window from which most recce photos seemed to have been taken.
The Stn Cdr at Heaven-in-Devon was always asking "How can you tell it's one of theirs, not one of ours?". So I joked to one mate that he should say that ours would be heading East, whereas theirs would be heading West. He then did so - and we all thought that the Stn Cdr was going to blow a gasket! But he realised he'd been out-witted by the Fg Off's union, so just stalked out with a face like thunder.
