And then there's arriving at a DTG, thinking it was a GR - and vice versa.

I recall two training areas in Germany (can't recall the names) which were exactly 100 km apart, due East/West.

So if you left out the prefix letters - and the (ground) Army never bothered with those! - you could easily be 100km wrong. And every service did it.
