When I joined up in the 60s issued with my kit was 3 pairs mens underpants white. They were the biggest baggiest pair of knicks that I had ever encountered. Also you had to stamp your name in black paint right down one leg. Imagine going ashore, trapping and then getting to home base. Any girl would have been so overcome with laughter that there would be no way of completing the action. I kept mine unworn for kit musters throughout basic training and part 2 training. After which they suddenly got consigned to the dustbin. My question is did anyone ever use them for their intended purpose?
