We all love animal mascots, but you better not take yours to the field if you’re in the Army. That’s right, mascots are banned because they might attract unwanted animals and have the potential to spread disease. So as much as you love your favorite team animal, they can’t come with you. Unless, of course, you’re in a K-9 unit that relies on heavily trained dogs. Then it’s not a mascot, but a service-member.
