Military exercise

Military exercises are organized training activities for armed forces. They allow military personnel to prepare for real operations without engaging in actual combat. These drills help leaders test new tactics and strategies in controlled environments. They also ensure that forces are ready for deployment before they leave their home bases.

There is a technical distinction between a military exercise and a war game. A military exercise involves full-scale operations using real military resources and functional equipment. These simulations attempt to reproduce the difficult conditions and decisions of wartime. In contrast, a war game is usually much smaller in scale. It typically uses artificial players to act out a model of a real-world scenario. War games often rely on mathematical modeling to provide quantifiable data. However, they are most frequently used to study qualitative factors.

Because war is not deterministic, war games cannot produce perfectly predictive results. Instead, they allow leaders to consider multiple possible outcomes for a single decision. Analysts look for cause-and-effect relationships within the simulated scenario. This is especially helpful for understanding complex geographic locations or positions. Some exercises focus specifically on the readiness of command staffs. These are called Command Post Exercises, or CPX. A CPX might run alongside a Field Training Exercise (FTX) to provide heavy emphasis on simulated events.

Exercises are categorized by the number of groups and nations involved. When different branches of the same nation train together, it is a joint exercise. If two nations work together based on security agreements, it is a bilateral exercise. If multiple nations participate, it is called a multilateral or coalition exercise. These activities allow for better coordination and observation of enemy tactics. They also serve as a visible show of cooperation and strength. A 2021 study found that joint exercises within alliances often deter adversaries. However, rare exercises conducted outside of alliances can sometimes lead to conflict escalation.

History shows that military training has evolved through many stages. Long ago, non-tactical games like chess and Go were used for strategy. In the early 19th century, Prussian officers developed modern tactical wargames. Around 1811, they created a game called Kriegsspiel. This game used dice to represent "friction," which included unpredictable factors like weather or morale. The Prussian army used these games to help win the Franco-Prussian War in 1870.

Technology changed the nature of training during the 20th century. In 1958, the Naval War College installed the Navy Electronic Warfare System. This computer-based system cost over $10 million to install. This shift meant that results became more dependent on quantitative data and analysis. During the Cold War, the RAND Corporation used game theory to model nuclear dissuasion. They used names like "SAM" for the U.S. and "IVAN" for the Soviet Union. This period also saw the study of the "prisoner's dilemma" to understand nuclear doctrine.

Modern training also includes complex simulations of human behavior and ethics. Soldiers often practice for roles that involve combat, humanitarian aid, or stabilization. These scenarios present ethical challenges where the right choice may not be clear. Personnel must follow specific regulations even when harm is a possible result. Some training uses high-tech tools like 360-degree technology or virtual battlefields. For example, DARPA has developed a serious game called DARWARS since 2003. These tools help soldiers manage sleep deprivation, time limits, and ambiguous information.
