Trivia: Which of these groups does NOT traditionally wear a campaign hat?
Canadian Mounties
Swiss Guards
U.S. Park Rangers
New Zealand Army
The correct answer is Swiss Guards
So why is this answer correct? : The campaign hat emerged in the 1840s when troops in the U.S. army began wearing civilian hats instead of the impractical shako (a cylindrical military cap). By the 1870s, a black felt version became regulation attire. The color and shape of the campaign hat has changed over time, but the popular design is still traditionally used by the Boy Scouts, Canadian Mounties, New Zealand Army, and U.S. Park Rangers, among others. The Swiss Guards, however, traditionally wear a black helmet or cap.
