Demobilization or demobilisation (see spelling differences) is the process of standing down a nation's armed forces from combat-ready status. This may be as a result of victory in war, or because a crisis has been peacefully resolved and military force will not be necessary. The opposite of demobilization is mobilization. Forceful demobilization of a defeated enemy is called demilitarization.
In the final days of World War II, for example, the United States Armed Forces developed a demobilization plan which would discharge soldiers on the basis of a point system that favoured length and certain types of service. The British armed forces were demobilised according to an "age-and-service" scheme.
The phrase demob happy refers to demobilization and is broadly applied to the feeling of relief at imminent release from a time-serving burden, such as a career. In the Russian language it is known as dembel and has become a certain tradition in the Soviet and post-Soviet Armed Forces. A United States equivalent is "short-timer's disease", comparable to "senioritis" among United States high-school students.
