An army (from Latin armata "armed (things)" via Old French armée, "armed" (feminine), in the broadest sense, is the land-based Military of a nation. It may also include other branches of the military such as the air force via means of aviation corps. Within a national military force, the word Army may also mean a field army, which is an operational formation, usually made up of one or more corps. A standing army is an army composed of full-time career soldiers who 'stand over', in other words, who do not disband during times of peace. They differ from army reserves who are activated only during such times as war or natural disasters. In several countries the army is officially called the land army to differentiate it from an air force called the air army, notably France. In such countries, the word "army" on its own retains its connotation of a land force in common usage. The current largest army in the world by number of active troops is People's Republic of China with 2.8 million strong Followed by United States with 1.45 million. India has 1.4 million soldiers and stands 3rd in the table of rankings.

An air force, also known in some countries as an air army or air corps, is in the broadest sense, the national military organization that primarily conducts aerial warfare. More specifically, it is the branch of a nation's armed services that is responsible for aerial warfare as distinct from an army, navy or other branch. Typically, air forces are responsible for gaining control of the air, carrying out strategic-bombing missions and providing support to surface forces. The term "air force" may also refer to a tactical air force or numbered air force, which is an operational formation within a national air force. Air forces typically consist of a combination of fighters, bombers, helicopters, transport planes and other aircraft. Many air forces are also responsible for operations of military space, intercontinental ballistic missiles (ICBM), and communications equipment. Some air forces may command and control other air-defence assets such as antiaircraft artillery, surface-to-air missiles, or anti-ballistic missile warning networks and defensive systems. As an organization, the air forces have "ground support" to support the pilots and aircrew. Similar to any civilian organization, there are supporting employees who assist and/or support other employees. Pilots cannot fly the aircraft without the assistance of other personnel such as engineers, loadmasters, fuels, and mechanics, and additional support-oriented career field.

A navy is the branch of a nation's armed forces principally designated for naval warfare and amphibious warfare; namely, lake- or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields; recent developments have included space related operations. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of nuclear missiles.

Space is the boundless, three-dimensional extent in which objects and events occur and have relative position and direction.[1] Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of the boundless four-dimensional continuum known as spacetime. In mathematics one examines 'spaces' with different numbers of dimensions and with different underlying structures. The concept of space is considered to be of fundamental importance to an understanding of the physical universe although disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Many of the philosophical questions arose in the 17th century, during the early development of classical mechanics. In Isaac Newton's view, space was absolute - in the sense that it existed permanently and independently of whether there were any matter in the space.[2] Other natural philosophers, notably Gottfried Leibniz, thought instead that space was a collection of relations between objects, given by their distance and direction from one another. In the 18th century, Immanuel Kant described space and time as elements of a systematic framework that humans use to structure their experience. In the 19th and 20th centuries mathematicians began to examine non-Euclidean geometries, in which space can be said to be curved, rather than flat. According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space.[3] Experimental tests of general relativity have confirmed that non-Euclidean space provides a better model for the shape of space.
