Land
Land, also known as dry land, ground, or earth, is the solid terrestrial surface of Earth not submerged by the ocean or another body of water. It makes up 29.2% of Earth's surface and includes all continents and islands. Earth's land surface is almost entirely covered by regolith, a layer of rock, soil, and minerals that forms the outer part of the crust. Land plays an important role in Earth's climate system, being involved in the carbon cycle, nitrogen cycle, and water cycle. One-third of land is covered in trees, another third is used for agriculture, and one-tenth is covered in permanent snow and glaciers. The remainder consists of desert, savannah, and prairie. Land terrain varies greatly, consisting of mountains, deserts, plains, plateaus, glaciers, and other landforms. In physical geology, the land is divided into two major categories: Mountain ranges and relatively flat interiors called cratons. Both form over millions of years through plate tect ...

Terrestrial Reconnaissance
Ground reconnaissance (also terrestrial reconnaissance, ground recon), is a type of reconnaissance that is employed along the elements of ground warfare Land warfare or ground warfare is the process of military operations eventuating in combat that takes place predominantly on the battlespace land surface of the Earth, planet. Land warfare is categorized by the use of large numbers of combat p .... It is the collection of intelligence that strictly involves routes, areas, zones (terrain-oriented); and the enemy (force-oriented). Ground reconnaissance is considered to be the most effective type of reconnaissance but also the slowest method in obtaining information about the terrain and enemy. Those units in contact with the enemy, especially patrols, are among the most reliable sources of information. Combat engineers are also good sources of information. These engineer units conduct engineer reconnaissance of an area and can provide detailed reporting on lines of commun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
