No, not ice hockey- field hockey! We were trained at the naval college to be able to play a wide variety of sports, because when we were "showing the flag" around the world to expatriate Brits, we would often engage in an informal game.
I can only actually remember one game of hockey, and I don't think I distinguished myself in anyway. However, I do remember that one would not need a playing field of grass: field hockey could be played on any reasonably level pitch.
I don't remember that we ever brought our own hockey sticks with us, instead relying on borrowed equipment.
