During World War II, British soldiers discovered that placing a condom over a gun’s barrel would keep the weapon dry and prevent it from corroding (near the sea) or icing up (in winter conditions).

No such condoms existed for larger weapons, however, and it was suggested to Winston Churchill one day that 18 long specimens be made to cover larger artillery pieces. Churchill agreed, with two stipulations. First, the larger condoms would clearly be labeled 'For Use By British Servicemen.' And second? The condoms would also be labeled 'Small.'
