uses its own map for its flag There are three distinct types of national flag for use on land, and three for use at sea, though many countries use identical designs for several (and sometimes all) of these types of flag.
On land On land, there is a distinction between
civil flags (
FIAV symbol ),
state flags (), and
war or military flags ().
Civil flags may be flown by anyone regardless of whether they are linked to government, whereas
state flags are those used officially by government agencies.
War flags (also called
military flags) are used by military organizations such as Armies, Marine Corps, or Air Forces. In practice, many countries (such as the
United States and the
United Kingdom) have identical flags for these three purposes;
national flag is sometimes used as a vexillological term to refer to such a three-purpose flag (). In a number of countries, however, and notably those in
Latin America, there is a distinction between civil and state flags. In most cases, the civil flag is a simplified version of the state flag, with the difference often being the presence of a coat of arms on the state flag that is absent from the civil flag. Very few countries use a war flag that differs from the state flag.
Taiwan,
Japan, and
China are notable examples of this.
Swallow-tailed flags are used as war flags and naval ensigns in
Nordic countries and charged versions as presidential or royal standards. The
Philippines does not have a distinctive war flag in this usual sense, but the
flag of the Philippines is legally unique in that it is flown with the red stripe on top when the country is in a state of war, rather than the conventional blue.
At sea The flag that indicates nationality on a ship is called an
ensign. As with the national flags, there are three varieties: the
civil ensign (), flown by private vessels;
state ensigns (also called
government ensigns; ), flown by government ships; and
war ensigns (also called
naval ensigns; ), flown by naval vessels. The ensign is flown from an ensign-staff at the
stern of the ship, or from a gaff when underway. Both these positions are superior to any other on the ship, even though the
masthead is higher. In the absence of a gaff the ensign may be flown from the
yardarm. (See
Maritime flags.) National flags may also be flown by aircraft and the land vehicles of important officials. In the case of aircraft, those flags are usually painted on, and those are usually to be painted on in the position as if they were blowing in the wind. In some countries, such as the
United States and
Canada (except for the
Royal Canadian Navy's Ensign), the national ensign is identical to the national flag, while in others, such as the
United Kingdom,
India,
Italy,
Japan and
Thailand, there are specific ensigns for maritime use. Most countries do not have a separate state ensign, although the United Kingdom is a rare exception, in having a
red ensign for civil use, a
white ensign as its naval ensign, and a
blue ensign for government non-military vessels. Italian naval ensign bears the arms of the
Italian Navy: a
shield, surmounted by a
turreted and
rostrum crown, which brings together in four parts the arms of four ancient
maritime republics (
Republic of Venice,
Republic of Genoa,
Republic of Pisa and
Republic of Amalfi).
Protocol flying a
Flag of North Korea. It is in height, over
Kijŏng-dong ("Peace village") near
Panmunjom, the border of
North Korea and
South Korea. There is a great deal of protocol involved in the proper display of national flags. A general rule is that the national flag should be flown in the position of honour, and not in an inferior position to any other flag (although some countries make an exception for royal standards). The following rules are typical of the conventions when flags are flown on land: • When a national flag is displayed together with any other flags, it must be hoisted first and lowered last. • When a national flag is displayed together with the national flags of other countries, all the flags should be of approximately equal size and must be flown at an equal height, although the national flag of the host country should be flown in the position of honour (in the centre of an odd number of flagpoles or at the far right — left from an observer's point of view — of an even number of flagpoles). • The flags of
Saudi Arabia,
Iraq,
Iran, and
Afghanistan are often wrapped from left to right (which appears right to left from an observer's point of view) because they contain Arabic text that must be displayed correctly. • When a national flag is displayed together with flags other than national flags, it should be flown on a separate flagpole, either higher or in the position of honour. • When a national flag is displayed together with any other flags on the same flagpole, it must be at the top, though separate flagpoles are preferable. • When a national flag is displayed together with any other flag on crossed flagpoles, the national flag must be on the observer's left and its flagpole must be in front of the flagpole of the other flag. • When a national flag is displayed together with another flag or flags in procession, the national flag must be on the marching right. If there is a row of flags, it should be in the position of honour. • When a national flag, with some exceptions, is flown upside down it indicates distress. This however is merely tradition. It is not a recognised distress signal according to the
International regulations for preventing collisions at sea. Further, a nation's flag is commonly flown inverted as a sign of protest or contempt against the country concerned. As of now, only the
flag of the Philippines recognises the distress symbolism of the reverse flag.
Hanging a flag vertically Most flags are hung vertically by rotating the flag pole. However, some countries have specific protocols for this purpose or even have special flags for vertical hanging; usually rotating some elements of the flag — such as the coat of arms — so that they are seen in an upright position. Examples of countries that have special protocol for vertical hanging are:
Canada,
Czech Republic,
Greece,
Israel, the
Philippines,
South Africa, and the
United States (reverse always showing); and the
United Kingdom (obverse always showing). Examples of countries that have special designs for vertical hanging are:
Austria,
Cambodia (coat of arms must be rotated 90° and blue strips are narrowed),
Dominica (coat of arms must be rotated and reverse always showing),
Germany,
Hungary,
Liechtenstein (crown must be rotated 90°),
Mexico,
Montenegro (coat of arms must be rotated 90° to normal position),
Nepal,
Slovakia (coat of arms must be rotated 90° to normal position), and
Saudi Arabia (
shahada must be rotated 90°). A vertical banner is used instead of the horizontal flag for
Malaysia. ==Design==
