Modern warfare

Modern warfare is warfare using the concepts, methods, and military technology that have come into use during and after World War II 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 combatants must modernize constantly to preserve their battle worthiness. Although total war was thought to be the form of international conflicts from the experience of the French Revolutionary Wars to World War II, the term no longer describes warfare in which a belligerent use all of its resources to destroy the enemy'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 the enemy'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 enemy 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.

Call of Duty

Call of Duty is a first-person shooter video game franchise. The series began on Microsoft Windows, and later expanded to consoles and handhelds. Several spin-off games have been released. The earlier games in the series are set primarily in World War II, including Call of Duty, Call of Duty 2, and Call of Duty 3.

Duty

Duty (from "due" meaning "that which is owing"; Old French: deu, did, past participle of devoir; Latin: debere, debitum, whence "debt") is a term that conveys a sense of moral commitment or obligation to someone or something. The moral commitment should result in action; it is not a matter of passive feeling or mere recognition. When someone recognizes a duty, that person theoretically commits himself to its fulfillment without considering their own self-interest. This is not to suggest that living a life of duty entirely precludes a life of leisure; however, its fulfillment generally involves some sacrifice of immediate self-interest. Typically, "the demands of justice, honor, and reputation are deeply bound up" with duty.

Cicero, an early philosopher who discusses duty in his work “On Duty", suggests that duties can come from four different sources:
