Drifting, but relevant, but during GW1 RAF aircrew, when asked, would reply that they were over MMFD. The USAF could hear this and it got to a point that they thought that we had a reference point that they were not aware of. They finally tabled a formal question asking the RAF where MMFD was? "That's easy" said the RAF," It stands for miles and miles of f****** desert"
Reminds me (I may have told it before). Consulting at BT about 96, there were two permanent staff STABs with whom I (only out about 7 years) got on just grand. One knew a PSI who'd been 15/19H. The other was an Engineer, specialising in mapping and charting (I'd once considered a job with Mapping and Charting Establishment Royal Engineers).
He'd been sent out to sandy parts at the end of Granby. He was tasked with marking 45 gallon drums with an 8-figure grid and planting them exactly every kilometre across the wasteland, using newfangled GPS.
He'd just about finished when he got called in for an interview without coffee because a unit had complained they were all 400m out.
It transpired that a troop of 14/20H had brought their shiny CR1s out from Tidworth, found a discrepancy between the grid and Troopy's GPS, so they set about dragging them all to the right place.
Then a grown-up had found them all moved to the wrong place.
Troopy promptly got a lesson on the theory of why Earth and satellite orbits are not perfect spheres, so that GPS needs recalibrating after you move ¼-way round the world, and how a GPS set for Tidworth is going to be 400m out in the Middle East.
Edit for mong Operation name recollection.
