what is badge

A badge is a device or accessory, often containing the insignia of an organization, which is presented or displayed to indicate some feat of service, a special accomplishment, a symbol of authority granted by taking an oath, or a sign of legitimate membership in a group or society. Badges can be made from various materials such as metal, plastic, leather, textile, and rubber, and they are commonly attached to clothing, bags, footwear, vehicles, and home electrical equipment. In the military, badges are used to denote the unit or arm to which the wearer belongs, as well as qualifications received through military training and rank. Similarly, youth organizations such as scouting and guiding use badges to show group membership, awards, and rank. Badges have a long history and were as popular as jewelry in the Middle Ages, varying from extremely expensive works of jewelry to simple mold-made badges in lead or other base metals. They are also used in political campaigning and are often given as part of a promotional campaign. In a broader sense, a badge can also refer to a characteristic mark, an emblem awarded for a particular accomplishment, or a distinctive mark worn as a sign of allegiance, membership, authority, or achievement.
