The main difference between Battle and War is that the Battle is a part of a war which is well defined in duration, area and force commitment and War is a organised and prolonged violent conflict between states
A battle is a combat in warfare between two or more armed forces. A war usually consists of multiple battles. Battles generally are well defined in duration, area, and force commitment. A battle with only limited engagement between the forces and without decisive results is sometimes called a skirmish.
Wars and military campaigns are guided by strategy, whereas battles take place on a level of planning and execution known as operational mobility. German strategist Carl von Clausewitz stated that “the employment of battles … to achieve the object of war” was the essence of strategy.
War is a state of armed conflict between states, governments, societies and informal paramilitary groups, such as mercenaries, insurgents and militias. It is generally characterized by extreme violence, aggression, destruction, and mortality, using regular or irregular military forces. Warfare refers to the common activities and characteristics of types of war, or of wars in general. Total war is warfare that is not restricted to purely legitimate military targets, and can result in massive civilian or other non-combatant suffering and casualties.
The scholarly study of war is sometimes called polemology ( POL-ə-MOL-ə-jee), from the Greek polemos, meaning “war”, and -logy, meaning “the study of”.
While some scholars see war as a universal and ancestral aspect of human nature, others argue it is a result of specific socio-cultural, economic, or ecological circumstances.
