Phase Line (cartography)
In cartography, a phase line is a line to show most often changing phases of a military operation, Military usage The term is also used in military terminology to refer to an imaginary line on a map used to coordinate phases of operations. They are usually distinguished with different code names, varying by the particulars of the mission such as location and nature. By the same token, phase lines are frequently used after a battle or a military campaign by historians to describe what territory was controlled by which side at a given phase of the campaign. Historical geography Historical geographers use such techniques in a similar way, but written upon a longer time period. Dated phase lines on a map would indicate the growth or shrinkage of a great power of the era such as the expansion of the Roman Empire, the spread of Islam or Christianity. Other familiar phase line mapping most experience in late elementary or middle school classes would be the extent of various ice ages ...

Cartography
Cartography (; from , 'papyrus, sheet of paper, map'; and , 'write') is the study and practice of making and using maps. Combining science, aesthetics and technique, cartography builds on the premise that reality (or an imagined reality) can be modeled in ways that communicate spatial information effectively. The fundamental objectives of traditional cartography are to: * Set the map's agenda and select traits of the object to be mapped. This is the concern of map editing. Traits may be physical, such as roads or land masses, or may be abstract, such as toponyms or political boundaries. * Represent the terrain of the mapped object on flat media. This is the concern of map projections. * Eliminate the mapped object's characteristics that are irrelevant to the map's purpose. This is the concern of Cartographic generalization, generalization. * Reduce the complexity of the characteristics that will be mapped. This is also the concern of generalization. * Orchestrate the elements ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Military Terminology
Military terminology refers to the terminology, terms and language of military organizations, military personnel, personnel, and military doctrine. Much like other forms of corporate jargon, military terminology is distinguishable from colloquial language by its use of new or repurposed words and phrases typically only understandable by current and former members of the military or associated companies and agencies. Common understanding The operational pressure for uniform understanding has developed since the early 20th century with the importance of Joint warfare, joint operations between different services (army, navy, air force) of the same country. International alliances and operations, including peacekeeping, have added additional complexity. For example, the NATO alliance now maintains a large dictionary of common terms for use by member countries. Development work is also taking place between NATO and Russia on common terminology for extended air defence, in English, Fre ...

Military Campaign
A military campaign is large-scale long-duration significant military strategy plan incorporating a series of interrelated military operations or battles forming a distinct part of a larger conflict often called a war. The term derives from the plain of Campania, a place of annual wartime operations by the armies of the Roman Republic. Definition 1. A military campaign denotes the time during which a given military force conducts combat operations in a given area (often referred to as AO, area of operation). A military campaign may be executed by either a single Armed Service, or as a combined services campaign conducted by land, naval, air, cyber, and space forces. 2. The purpose of a military campaign is to achieve a particular desired resolution of a military conflict as its strategic goal. This is constrained by resources, geography and/or season. A campaign is measured relative to the technology used by the belligerents to achieve goals, and while in the pre-indus ...

Historian
A historian is a person who studies and writes about the past and is regarded as an authority on it. Historians are concerned with the continuous, methodical narrative and research of past events as relating to the human species; as well as the study of all history in time. Some historians are recognized by publications or training and experience.Herman, A. M. (1998). Occupational outlook handbook: 1998–99 edition. Indianapolis: JIST Works. Page 525. "Historian" became a professional occupation in the late nineteenth century as research universities were emerging in Germany and elsewhere. Objectivity Among historians Ancient historians In the 19th century, scholars used to study ancient Greek and Roman historians to see how generally reliable they were. In recent decades, however, scholars have focused more on the constructions, genres, and meanings that ancient historians sought to convey to their audiences. History is always written with contemporary concerns and ancient hist ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Great Power
A great power is a sovereign state that is recognized as having the ability and expertise to exert its influence on a global scale. Great powers characteristically possess military and economic strength, as well as diplomatic and soft power influence, which may cause middle or small powers to consider the great powers' opinions before taking actions of their own. International relations theorists have posited that great power status can be characterized into power capabilities, spatial aspects, and status dimensions. While some nations are widely considered to be great powers, there is considerable debate on the exact criteria of great power status. Historically, the status of great powers has been formally recognized in organizations such as the Congress of Vienna of 1814–1815Danilovic, Vesna.

Ice Age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages, and greenhouse periods during which there are no glaciers on the planet. Earth is currently in the ice age called Quaternary glaciation. Individual pulses of cold climate within an ice age are termed '' glacial periods'' (''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called '' interglacials'' or ''interstadials''. In glaciology, the term ''ice age'' is defined by the presence of extensive ice sheets in the northern and southern hemispheres. By this definition, the current Holocene epoch is an interglacial period of an ice age. The accumulation of anthropogenic greenhouse gases is projected to delay the next glacial period.
