Jan Fischer, American Soldier In His Military Life

Military in combat
The primary reason for the existence of the military is to engage in combat, should it be required to do so by the national defense policy, and to win. This represents an organizational goal of any military, and the primary focus for military thought through military history.
The "show" of military force has been a term that referred as much to military force projection, as to the units such as regiments or gunboats deployed in a particular theatre, or as an aggregate of such forces. In the Gulf War the United States Central Command controlled military forces (units) of each of the four military services of the United States. How victory is achieved, and what shape it assumes is studied by most, if not all, military groups on three levels.
