I served in No. 40 Commando during the late 50s to early 60's and completed commando training in the style of Achnacarry. Our playground had changed to Dartmoor with live firing at the Willsworthy range.
There were no differences between wartime and peacetime training practices. We were fit - very fit, with hikes of 25 - 30 miles with a full Bergen being the norm, the term 'yomp' wasn't then in use, Such was the international reputation of the Commando's, we trained specialist forces from around the world.
Wonderful times !
