Military

The organized land, sea, and air forces maintained by a state for defense and warfare. It includes personnel, command structures, equipment, and supporting institutions.

Army: A state's organized land force, trained and equipped to conduct operations on land. The army is the military's principal land-warfare branch.
Military doctrine: A military's principles for preparing, organizing, and employing forces to achieve strategic and operational goals. Doctrine guides how military capabilities are turned into action.
Police: A public institution authorized to enforce domestic law and maintain public order. Police primarily enforce domestic law, unlike armed forces organized for defense and warfare.
Deterrence theory: The theory that credible threats of retaliation can discourage an adversary from taking an unwanted action. Military capabilities can deter attacks by making their expected costs prohibitive.
Navy: A state's organized maritime force, equipped to operate at sea and project power from the water. The navy carries out the military's maritime missions.
Military strategy: The use of military resources to achieve political objectives through threats or armed force. Strategy connects military action to the state's political aims.
Paramilitary: An organization structured and trained like a military force but not formally part of a state's regular armed forces. Paramilitary organizations resemble military forces without the same formal status.
Militarism: The belief that a state should maintain strong armed forces and rely on military power in policy. A society's military institutions can influence political priorities and public life.
Air force: A state's organized aerial force, responsible for military operations using aircraft and other airborne systems. The air force provides the military's dedicated aerial branch.
Conscription: Compulsory enrollment of people into a state's armed forces or national service. Conscription is one method states use to recruit military personnel.
