What type of flag is known as a 'Guidon'?

A Guidon is specifically characterized as a swallow-tailed flag that represents military organizations, particularly at the company level. It serves as a symbol of identity and cohesion for units, often bearing the unit's insignia, which enhances morale and pride among soldiers. This design is distinct from other flags, such as those used by mounted units or ships. The swallow-tailed shape is particularly functional in the field, allowing for easier visibility and identification in various conditions, which is why it is used at the company level rather than being associated with larger units or different purposes. The distinctiveness of the Guidon reinforces its role within Army tradition and organization, specifying it clearly as a unit identifier for companies and similar formations.
