I was on Salisbury plain with our Puma and Wessex in the 70's and we had some TA arrive to play trooping and roping etc, they impressed the heck out of me in their dedication etc, their unit had travelled a long distance, (Bristol comes to mind) to take part and their fuel allowance wouldn't cover it, so they had been begging, stealing and borrowing fuel for the 4 tonner for months to allow them to take part, and they made the most of the opportunity.
They were game to try everything and put their new found skills to the test, they went away happy and better for it.
