Modern Warfare

Modern warfare, although present in every historical period of military history, is generally used to refer to the concepts, methods and technologies that have come into use during and after the Second World War and the Korean War. The concepts and methods have assumed more complex forms of the 19th- and early-20th-century antecedents, largely due to the widespread use of highly advanced information technology, and modern armies must modernize constantly to preserve their battleworthiness.

Although total war was thought to be the form of international conflicts from the experience of the French Revolutionary Wars to the Second World War, the term no longer describes warfare in which countries or nations use all of their resources to destroy another country's or nation's organized ability to engage in war. The practice of total war which had been in use for over a century, as a form of war policy, has been changed dramatically with greater awareness of tactical, operational and strategic battle information.

War in modern times has been the inclusion of civilians and civilian infrastructure as targets in destroying a country's ability to engage in war. The targeting of civilians developed from two distinct theories. The first theory was that if enough civilians were killed, factories could not function. The second theory was that if civilians were killed, the country would be so demoralized that it would have no ability to wage further war. However UNICEF reports that civilian fatalities are down from 20 percent prior to 1900 AD to less than 5 percent of fatalities in the wars beginning in the 1990s.

With the advent of nuclear weapons, the concept of full-scale war carries the prospect of global annihilation, and as such conflicts since WWII have by definition been "low intensity" conflicts, typically in the form of proxy wars fought within local regional confines, using what are now referred to as "conventional weapons," typically combined with the use of asymmetric warfare tactics and applied use of intelligence.

More recently the US Department of Defense introduced a concept of Battlespace as the integrated information management of all significant factors that impact on combat operations by armed forces for the military theatre of operations, including information, air, land, sea and space. It includes the environment, factors and conditions that must be understood to successfully apply combat power, protect the force, or complete the mission. This includes enemy and friendly forces; facilities, weather and terrain within the operational areas and areas of interest.
