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.
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.
The ensign is a maritime flag that is used for the national identification of a ship. The ensign is the largest flag, generally flown at the stern (rear) of the ship while in port. In ports, depending on the ship's origin, it is sometimes identical with a jack on the bow of the ship. Jacks are more common on warships than on merchant ships.
The national flag of Saudi Arabia, also known as the al-Alam, is a green background with Arabic inscription and a sword in white. The inscription is the Islamic creed, or shahada: "There is no deity but God; Muhammad is the Messenger of God". The current design has been used by the government of Saudi Arabia since 15 March 1973.
The national flag of Spain, as it is defined in the Constitution of 1978, consists of three horizontal stripes: red, yellow and red, the yellow stripe being twice the height of each red stripe. Traditionally, the middle stripe was defined by the more archaic term of gualda, and hence the popular name la Rojigualda (red-weld).
A jack is a flag flown from a short jackstaff at the bow (front) of a vessel, while the ensign is flown on the stern (rear). Jacks on bowsprits or foremasts appeared in the 17th century. A country may have different jacks for different purposes, especially when the naval jack is forbidden to other vessels. The United Kingdom has an official civil jack; the Netherlands has several unofficial ones. In some countries, ships of other government institutions may fly the naval jack, e.g. the ships of the United States Coast Guard and the National Oceanic and Atmospheric Administration in the case of the US jack. Certain organs of the UK's government have their own departmental jacks. Commercial or pleasure craft may fly the flag of an administrative division or municipality at the bow. Merchant ships may fly a house flag. Yachts may fly a club burgee or officer's flag or the owner's private signal at the bow. Practice may be regulated by law, custom, or personal judgment.
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.
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 flag of Nazi Germany, officially the flag of the German Reich, featured a red background with a black swastika on a white disc. This flag came into use initially as the banner of the Nazi Party (NSDAP) after its foundation. Following the appointment of Adolf Hitler as Chancellor in 1933, this flag was adopted as mandatory for use, while the national one was the black-white-red triband of the German Empire.
The following is a list of historical military colours, standards and guidons in different countries that do not exist today.
Uma-jirushi were massive flags used in feudal Japan to identify a daimyō or equally important military commander on the field of battle. They came into prominence during the Sengoku period. While many were simply large flags, not very different from sashimono or hata-jirushi, most were three-dimensional figures, more like kites, and in the shape of bells, gongs, umbrellas, or streamers.
A civil ensign is an ensign used by civilian vessels to denote their nationality. It can be the same or different from the state ensign and the naval ensign. It is also known as the merchant ensign or merchant flag. Some countries have special civil ensigns for yachts, and even for specific yacht clubs, known as yacht ensigns.
The Cross of Burgundy is a saw-toothed form of the Cross of Saint Andrew, the patron saint of Burgundy, and a historical banner and battle flag used by holders of the title of Duke of Burgundy and their subjects.
A naval ensign is an ensign used by naval ships of various countries to denote their nationality. It can be the same or different from a country's civil ensign or state ensign.
In heraldry and vexillology, a heraldic flag is a flag containing coats of arms, heraldic badges, or other devices used for personal identification.
Military aircraft insignia are insignia applied to military aircraft to identify the nation or branch of military service to which the aircraft belong. Many insignia are in the form of a circular roundel or modified roundel; other shapes such as stars, crosses, squares, or triangles are also used. Insignia are often displayed on the sides of the fuselage, the upper and lower surfaces of the wings, as well as on the fin or rudder of an aircraft, although considerable variation can be found amongst different air arms and within specific air arms over time.
The three branches of the Australian Defence Force are each represented by flags, among other emblems and insignia. Within each service, various symbols fly on individual ships, at bases, camps, the Australian Defence Force Academy and colleges. These include flags, standards, guidons and banners and that denote rank, appointment, corps, formations, regiments, training units and sub-units.
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.
