Hi All, Does anybody have any idea of the history of said tests, such as what they were and when they changed/evolved. I know for example that at Achnacarry, they didn't do a 30-miler and the speed marches were of 15/16 miles, but I don't know the full extent of the tests there. I've heard that the 30-miler was introduced after the Falklands, though I'm not sure. So, anybody got any info on 'em? I ask purely as a matter if interest.
