Military in the context of STANAG

A political union is a type of political entity which is composed of, or created from, smaller polities or the process which achieves this. These smaller polities are usually called federated states and federal territories in a federal government; they are called prefectures, regions, or provinces in the case of a centralised government. This form of government may be created through voluntary and mutual cession and is described as unionism by its constituent members and proponents. In other cases, it may arise from political unification, characterised by coercion and conquest. The unification of separate states which, in the past, had together constituted a single entity is known as reunification. Unlike a personal union or real union, the individual constituent entities may have devolution of powers but are subordinate to a central government or coordinated in some sort of organization. In a federalised system, the constituent entities usually have internal autonomy, for example in the setup of police departments, and share power with the federal government, for whom external sovereignty, military forces, and foreign affairs are usually reserved. The union is recognised internationally as a single political entity. A political union may also be called a legislative union or state union.A union may be effected in many forms, broadly categorized as:

• Incorporating union
• Incorporating annexation
• Federal union
• Federative annexation
• Mixed unions

The World Factbook, also known as the CIA World Factbook, is a reference resource produced by the United States' Central Intelligence Agency (CIA) with almanac-style information about the countries of the world. The official print version is available from the Government Publishing Office. The Factbook is available in website and downloadable formats. It provides a two- to three-page summary of the demographics, geography, communications, government, economy, and military of 258 international entities, including U.S.-recognized countries, dependencies, and other areas in the world.

The World Factbook is prepared by the CIA for the use of U.S. government officials, and its style, format, coverage, and content are primarily designed to meet their requirements. It is also frequently used as a resource for academic research papers and news articles. As a work of the U.S. government, it is in the public domain in the United States.

The Singapore Armed Forces (SAF) are the military of the Republic of Singapore, responsible for protecting and defending the security interests and the sovereignty of the country. A component of the Ministry of Defence (MINDEF), the armed forces have four service branches: the Army, Navy, Air Force, and Digital and Intelligence Service. An integrated force, it is the most capable, robust, technologically sophisticated and powerful military in the Southeast Asia region. The SAF is headed by the chief of defence force, appointed by the President, on the advice of the Cabinet.

Since its inception, the SAF has been involved in various operations, both domestically and abroad. These include peacekeeping missions in places such as Afghanistan, Iraq and Timor Leste as well as disaster relief operations in various countries, including the 1970 Bhola cyclone, 2004 Indian Ocean earthquake and tsunami, Hurricane Katrina, 2008 Sichuan earthquake, April 2015 Nepal earthquake, Hurricane Harvey, among others. In addition, the SAF has assisted the United Nations to oversee and supervise the electoral process in countries such as Cambodia, Ethiopia, Namibia and South Africa.

Combined arms is an approach to warfare that seeks to integrate different combat arms of a military to achieve mutually complementary effects—for example, using infantry and armour in an urban environment in which each supports the other.

According to the strategist William S. Lind, combined arms can be distinguished from the concept of "supporting arms" as follows:

A commander-in-chief or supreme commander (supreme commander-in-chief) is the person who exercises supreme command and control over an armed force or a military branch. As a technical term, it refers to military competencies that reside in a country's executive leadership, a head of state, head of government, or other designated government official.

While often used interchangeably, the title of Supreme Commander–in–Chief is technically different, since the two titles can be in use simultaneously. For example, in the case of the Armed Forces of Ukraine, the supreme commander-in-chief is the president of Ukraine, while the commander-in-chief is its professional head.

A think tank, or public policy institute, is an organization that performs research and advocacy concerning topics such as social policy, political strategy, economics, military, technology, and culture. Most think tanks are non-governmental organizations, but some are semi-autonomous agencies within a government, and some are associated with particular political parties, businesses, or the military. Think tanks are often funded by individual donations, with many also accepting government grants.

Think tanks publish articles and studies, and sometimes draft legislation on particular matters of policy or society. This information is then used by governments, businesses, media organizations, social movements, or other interest groups. Think tanks range from those associated with highly academic or scholarly activities to those that are overtly ideological and pushing for particular policies, with a wide range among them in terms of the quality of their research. Later generations of think tanks have tended to be more ideologically oriented.

The police are a constituted body of people empowered by a state with the aim of enforcing the law and protecting the public order as well as the public itself. This commonly includes ensuring the safety, health, and possessions of citizens, and to prevent crime and civil disorder. Their lawful powers encompass arrest and the use of force legitimized by the state via the monopoly on violence. The term is most commonly associated with the police forces of a sovereign state that are authorized to exercise the police power of that state within a defined legal or territorial area of responsibility. Police forces are often defined as being separate from the military and other organizations involved in the defense of the state against foreign aggressors; however, gendarmerie are military units charged with civil policing. Police forces are usually public sector services, funded through taxes.

Law enforcement is only part of policing activity. Policing has included an array of activities in different situations, but the predominant ones are concerned with the preservation of order. In some societies, in the late 18th and early 19th centuries, these developed within the context of maintaining the class system and the protection of private property. Police forces have become ubiquitous and a necessity in complex modern societies. However, their role can sometimes be controversial, as they may be involved to varying degrees in corruption, brutality, and the enforcement of authoritarian rule.

The British Overseas Territories (BOTs) are fourteen territories that maintain a constitutional or historically recognised connection with the United Kingdom (UK) and constitute part of its sovereign territory, yet lie outside the British Islands. These territories are remnants of the former British Empire which remained under British sovereignty following decolonisation, albeit with varying constitutional statuses.

The permanently inhabited territories exercise varying degrees of internal self-governance, although the UK retains ultimate constitutional oversight, and authority over defence, foreign relations and internal security. While three of the territories are inhabited primarily by military or scientific personnel, the remainder host substantial civilian populations. All fourteen territories recognise the British monarch as head of state and oversight is primarily exercised by the Foreign, Commonwealth and Development Office (FCDO). The total land area of all the BOTs make up 18,015 km (6,956 sq mi), roughly the size of Fiji, which was itself a former British colony.

A tyrant (from Ancient Greek τύραννος (túrannos) 'absolute ruler'), in the modern English usage of the word, is an absolute ruler who is unrestrained by law, or one who has usurped a legitimate ruler's sovereignty. Often portrayed as cruel, tyrants may defend their positions by resorting to repressive means. The original Greek term meant an absolute sovereign who came to power without constitutional right, yet the word had a neutral connotation during the Archaic and early Classical periods. However, Greek philosopher Plato saw tyrannos as a negative form of government, and on account of the decisive influence of philosophy on politics, deemed tyranny the "fourth and worst disorder of a state."

The philosophers Plato and Aristotle defined a tyrant as a person who rules without law, using extreme and cruel methods against both his own people and others. The Encyclopédie defined the term as a usurper of sovereign power who makes "his subjects the victims of his passions and unjust desires, which he substitutes for laws".In the late fifth and fourth centuries BC, a new kind of tyrant, one who had the support of the military, arose – specifically in Sicily.

War is an armed conflict between the armed forces of states, or between governmental forces and armed groups that are organized under a certain command structure and have the capacity to sustain military operations, or between such organized groups.

It is generally characterized by widespread violence, destruction, and mortality, using regular or irregular military forces. Warfare refers to the common activities and characteristics of types of war, or of wars in general.

A mercenary is a private individual who joins an armed conflict for personal profit, is otherwise an outsider to the conflict, and is not a member of any other official military. Mercenaries fight for money or other forms of payment rather than for political interests.

Beginning in the 20th century, mercenaries have increasingly come to be seen as less entitled to protection by rules of war than non-mercenaries. The Geneva Conventions declare that mercenaries are not recognized as legitimate combatants and do not have to be granted the same legal protections as captured service personnel of the armed forces. In practice, whether or not a person is a mercenary may be a matter of degree, as financial and political interests may overlap.

Conservatism is a cultural, social, and political philosophy and ideology that seeks to promote and preserve traditional institutions, customs, and values. The central tenets of conservatism may vary in relation to the culture and civilization in which it appears. In Western culture, depending on the particular nation and the particular time period, conservatives seek to promote and preserve a range of institutions, such as the nuclear family, organized religion, the military, the nation-state, property rights, rule of law, aristocracy, and monarchy.

The 18th-century Anglo-Irish statesman Edmund Burke, who opposed the French Revolution but supported the American Revolution, is credited as one of the forefathers of conservative thought in the 1790s along with Savoyard statesman Joseph de Maistre. The first established use of the term in a political context originated in 1818 with François-René de Chateaubriand during the period of Bourbon Restoration that sought to roll back the policies of the French Revolution and establish social order.

Realism, in international relations theory, is a theoretical framework that views world politics as an enduring competition among self-interested states vying for power and positioning within an anarchic global system devoid of a centralized authority. It centers on states as rational primary actors navigating a system shaped by power politics, national interest, and a pursuit of security and self-preservation.

Realism involves the strategic use of military force and alliances to boost global influence while maintaining a balance of power. War is seen as inevitably inherent in the anarchic conditions of world politics. Realism also emphasizes the complex dynamics of the security dilemma, where actions taken for security reasons can unintentionally lead to tensions between states.

A military junta (/ˈhʊntə, ˈdʒʌntə/ ) is a system of government led by a committee of military leaders. The term junta means "meeting" or "committee" and originated in the national and local junta organized by the Spanish resistance to Napoleon's invasion of Spain in 1808. The term is now used to refer to an authoritarian form of government characterized by a politically dominant group of military officers.

Militarism is the belief or the desire of a government or a people that a state should maintain a strong military capability and to use it aggressively to expand national interests and/or values. It may also imply the glorification of the military and of the ideals of a professional military class and the "predominance of the armed forces in the administration or policy of the state" (see also: stratocracy and military junta).

A coalition is formed when two or more people or groups temporarily work together to achieve a common goal. The term is most frequently used to denote a formation of power in political, military, or economic spaces.

The Kingdom of the Netherlands, commonly known simply as the Netherlands, is a sovereign state consisting of a collection of constituent territories united under the monarch of the Netherlands, who functions as head of state. The realm is not a federation; it is a unitary monarchy with its largest subdivision, the eponymous Netherlands, predominantly located in Northwestern Europe and with several smaller island territories located in the Caribbean.

The four subdivisions of the Kingdom—Aruba, Curaçao, the Netherlands, and Sint Maarten—are constituent countries (landen in Dutch; singular: land) and participate on a basis of equality as partners in the Kingdom. In practice, however, most of the Kingdom's affairs are administered by the Netherlands—which comprises roughly 98% of the Kingdom's land area and population—on behalf of the entire Kingdom. Consequently, Aruba, Curaçao, and Sint Maarten are dependent on the Netherlands for matters like foreign policy and defence, but are autonomous to a certain degree, with their own parliaments.
