For millennia, the sight of a flag snapping in the wind has signaled more than just a national border; in the heat of battle, it served as a lifeline. Military colours—the collective term for flags, standards, and guidons—are deeply symbolic objects that represent the honor, history, and identity of a military unit.
The practice of carrying these markers is believed to have originated in Ancient Egypt approximately 5,000 years ago. Later, the Roman Empire utilized vexilla (battle standards) emblazoned with "SPQR" to organize their legions. By the High Middle Ages in Europe, these traditions were formalized, with standards often featuring the commander's coat of arms to mark their location on the battlefield.
In the age of line tactics, the unit colour was an important rallying point for infantry soldiers.

Rallying Points: Historically, colours served as critical visual markers for soldiers to regroup during the chaos of line tactics.
Battle Honours: Many flags feature embroidered names of past victories, preserving a unit's combat legacy.
Hierarchy of Flags: Different terms are used based on the unit: "Colours" for infantry, "Standards" for cavalry, and "Guidons" for smaller detachments.
Strict Etiquette: National colours are typically never "dipped" (lowered) in salute, whereas organizational colours often are.

Commonwealth and British Traditions
In the United Kingdom and Commonwealth nations, a distinction is often made between the King's Colour (representing the monarch) and the Regimental Colour (representing the unit). For example, the Foot Guards' King's colours are crimson, while their regimental colours are based on the Union Flag.

North American Practices
In the United States military, each branch utilizes an organizational colour (ceremonial flag) measuring 4 ft 4 in by 5 ft 6 in. These are paraded alongside a National Color of equal dimensions. While the National Color remains vertical, organizational colours and guidons are dipped during salutes.

The U.S. Army utilizes a National Color (a fringed version of the national flag) and an Organizational Color. The latter features the eagle from the Great Seal of the United States and is adorned with campaign streamers, which serve as the American equivalent to embroidered battle honours.

What is the difference between a colour and a guidon?
A colour is typically a larger flag used by infantry regiments, whereas a guidon is a smaller, often swallow-tailed flag used by cavalry or smaller company-sized units for tactical identification.
What are battle honours?
Battle honours are the names of significant engagements or campaigns in which a unit distinguished itself. These are often embroidered directly onto the fabric of the colours or attached as streamers.
Why are some flags "dipped" and others not?
In many military traditions, the National Colour represents the sovereignty of the state and is never dipped in salute. Organizational or regimental colours, however, are dipped as a sign of respect to a higher authority or during specific ceremonies.
What happens to colours when they are no longer in use?
When colours become too worn or a unit is disbanded, they are often "laid up" in a sacred or official place, such as a cathedral, chapel, or museum, where they remain until they naturally decay.
