I learned how to drive a tank because I wanted to be in the Armoured Corps. In Vietnam, I was based in Nui Dat. I was in the lead tank on one operation where we worked with the Americans. We carried 20-litre water drums and worked out how to have a hot shower using the heat coming off the tank’s engine. However, the Americans had a semitrailer with a full bain-marie: chicken, steak, all kind of things. Anybody could walk in, day or night, and help themselves to a feed. It was unbelievable.
