War, to become known as one, must entail some degree of confrontation using weapons and other military technology and equipment by armed forces employing military tactics and operational art within the broad military strategy subject to military logistics. War Studies by military theorists throughout military history have sought to identify the philosophy of war, and to reduce it to a military science. In general, modern military science considers several factors before a National defence policy is created to allow a war to commence: the environment in the area(s) of combat operations, the posture national forces will adopt on the commencement of a war, and the type of warfare troops will be engaged in. Conventional warfare is an attempt to reduce an opponent’s military capability through open battle. It is a declared war between existing states in which nuclear, biological, or chemical weapons are not used or only see limited deployment in support of conventional military goals and maneuvers. The opposite of conventional warfare, unconventional warfare, is an attempt to achieve military victory through acquiescence, capitulation, or clandestine support for one side of an existing conflict. Nuclear warfare is warfare in which nuclear weapons are the primary, or a major, method of coercing the capitulation of the other side, as opposed to a supporting tactical or strategic role in a conventional conflict. Civil war is a war where the forces in conflict belong to the same nation or political entity and are vying for control of or independence from that nation or political entity. Asymmetric warfare is a conflict between two populations of drastically different levels of military capability or size. The publication is timely in view of the impressive development of the methods and techniques with their application to understanding the subject.
