I do have vivid memories of digging a little hole away from the firefight in the 'designated' area, several hours after sundown.
I had a healthy supply of white gold to hand, a balmy breeze to caress the nether regions as I assumed the position, for a leisurely solving of a problem caused by several days of trail rations.
I was at peace with the world.
Then .....
....a bloody hyena whooped behind me.
I had the paperwork, finished, signed off and was on my way back to the fireside faster than Ussein Bolt could get out of the starting blocks.
So if any of you are ever constipated, try taking a dump in the dark around hyenas.
Tell that one to your cadets...... poor burgers will have to hold hands to take a whizzes.
