The significance of the guidon is that it represents the unit and its commandingofficer. When the commander is in, his or her guidon is displayed for everyone to see. When he leaves for the day, the guidon is taken down. It is an honor, although sometimes a dubious one, to be the guidon carrier for a unit, known as a "guidon bearer" or "guide". He or she stands in front of the unit alongside of the commander (or the commander's representative), and is the rallying point for troops to fall into formation when the order is given. In drill and ceromonies, the guidon and commander are always in front of the formation.
