A flag is a piece of fabric with a distinctive design and colours. It is used as a symbol, a signalling device, or for decoration. The term flag is also used to refer to the graphic design employed, and flags have evolved into a general tool for rudimentary signalling and identification, especially in environments where communication is challenging. Many flags fall into groups of similar designs called flag families. The study of flags is known as "vexillology" from the Latin vexillum, meaning "flag" or "banner".
A national flag is a flag that represents and symbolizes a given nation. It is flown by the government of that nation, but can also be flown by its citizens. A national flag is typically designed with specific meanings for its colours and symbols, which may also be used separately from the flag as a symbol of the nation. The design of a national flag is sometimes altered after the occurrence of important historical events. The burning or destruction of a national flag is a greatly symbolic act.
The Roman legion, the largest military unit of the Roman army, was composed of Roman citizens serving as legionaries. During the Roman Republic the manipular legion comprised 4,200 infantry and 300 cavalry. After the Marian reforms in 107 BC the legions were formed of 5,200 men and were restructured around 10 cohorts, the first cohort being double strength. This structure persisted throughout the Principate and middle empire, before further changes in the fourth century resulted in new formations of around 1,000 men.
In military organizations, a colour guard is a detachment of soldiers assigned to the protection of regimental colours and the national flag. This duty is highly prestigious, and the military colour is generally carried by a young officer (ensign), while experienced non-commissioned officers are assigned to the protection of the national flag. These non-commissioned officers, accompanied in several countries by warrant officers, can be ceremonially armed with either sabres or rifles to protect the colour. Colour guards are generally dismounted, but there are also mounted colour guard formations as well.
Military ranks are a system of hierarchical relationships, within armed forces, police, intelligence agencies or other institutions organized along military lines. The military rank system defines dominance, authority, and responsibility in a military hierarchy. It incorporates the principles of exercising power and authority into the military chain of command—the succession of commanders superior to subordinates through which command is exercised. The military chain of command constructs an important component for organized collective action.
A cohort was a standard tactical military unit of a Roman legion. Although the standard size changed with time and situation, it was generally composed of 480 soldiers. A cohort is considered to be the equivalent of a modern military battalion. The cohort replaced the maniple. From the late second century BC and until the middle of the third century AD, ten cohorts made up a legion. Cohorts were named "first cohort", "second cohort", etc. The first cohort consisted of experienced legionaries, while the legionaries in the tenth cohort were less experienced.
Trooping the Colour is a ceremonial event performed every year on Horse Guards Parade in London, United Kingdom, by regiments of Household Division, to celebrate the official birthday of the British sovereign. It is also known as the Sovereign's Birthday Parade. Similar events are held in other countries of the Commonwealth. In the UK, it is, with the State Opening of Parliament, the biggest event of the ceremonial calendar, and watched by millions on TV and on the streets of London.
Drill commands are generally used with a group that is marching, most often in military foot drills or in a marching band. Drill commands are usually heard in major events involving service personnel, reservists and veterans of a country's armed forces, and by extension, public security services and youth uniformed organizations.
Ensign is a junior rank of a commissioned officer in the armed forces of some countries, normally in the infantry or navy. As the junior officer in an infantry regiment was traditionally the carrier of the regimental colours, the rank acquired the name. This rank has generally been replaced in army ranks by second lieutenant. Ensigns were generally the lowest-ranking commissioned officer, except where the rank of subaltern existed. In contrast, the Arab rank of ensign, لواء, liwa', derives from the command of units with an ensign, not the carrier of such a unit's ensign, and is today the equivalent of a major general.
A military uniform is a standardised dress worn by members of the armed forces and paramilitaries of various nations.
In military organizations, the practice of carrying colours, standards, flags, or guidons, both to act as a rallying point for troops and to mark the location of the commander, is thought to have originated in Ancient Egypt some 5,000 years ago. The Roman Empire also made battle standards reading SPQR a part of their vast armies. It was formalized in the armies of Europe in the High Middle Ages, with standards being emblazoned with the commander's coat of arms.
The following is a list of historical military colours, standards and guidons in different countries that do not exist today.
An aquila was a prominent symbol used in ancient Rome, especially as the standard of a Roman legion. A legionary known as an aquilifer, the "eagle-bearer", carried this standard. Each legion carried one eagle.
A signifer was a standard bearer of the Roman legions. He carried a signum (standard) for a cohort or century. Each century had a signifer so there were 60 in a legion. Within each cohort, the first century's signifer would be the senior one. The -fer in signifer comes from ferre, the Latin for 'to bear' or 'to carry'.
A battle honour is an award of a right by a government or sovereign to a military unit to emblazon the name of a battle or operation on its flags ("colours"), uniforms or other accessories where ornamentation is possible.
The Regulation Colours are the standard colours used in the armed forces of the countries of the Commonwealth of Nations.
The Presentation of Colours is a military ceremony that marks an anniversary or significant event in the history of a particular regiment or similar military unit. This involves the presentation of a new version of the regimental colour to a regiment or equivalent formation in their respective armed forces service branch. This is a traditional ceremony that was pioneered by the British Armed Forces, and is today used in most Commonwealth countries.
An insignia is a sign or mark distinguishing a group, grade, rank, or function. It can be a symbol of personal power or that of an official group or governing body.
