Military exercise

A planned activity in which armed forces practice tactics, operations, or coordination, often through simulated combat or field maneuvers.

Command and control: The systems and processes commanders use to direct forces and coordinate operations. Exercises test whether commanders can issue orders and coordinate units under pressure.
Readiness: The ability of a military force to deploy and perform assigned missions. Exercise results help assess whether units can carry out missions when required.
Prussian General Staff: The military institution that planned Prussia’s wars and shaped modern professional staff systems. Its planning and training methods helped formalize preparation for large-scale operations.
Deterrence: A strategy that seeks to prevent an action by threatening unacceptable costs or denying its benefits. Exercises can demonstrate military capability in ways intended to discourage aggression.
Wargaming: The use of structured games to explore decisions and outcomes in military or strategic situations. Some exercises rehearse decisions through simulated opponents rather than field maneuvers.
Interoperability: The ability of different military forces or systems to operate together effectively. Multinational exercises reveal gaps in shared procedures, communications, and equipment.
Kriegsspiel: A nineteenth-century Prussian tactical wargame used to train officers in battlefield decision-making. This influential training game made simulated command decisions part of officer education.
Security dilemma: A situation in which one state’s defensive measures make others feel less secure and prompt countermeasures. A drill meant as reassurance or preparation can appear threatening to neighboring states.
After-action review: A structured examination of an activity to identify what happened, why, and what should change. Reviewing performance turns exercise experience into specific lessons and corrections.
Joint warfare: Military operations coordinated across multiple armed services, such as land, sea, and air forces. Exercises rehearse the coordination needed to combine capabilities across services.
