The Selective Service Act of 1948, enacted in June of that year, created a new and separate system, the basis for the modern system. All men 18 years and older had to register with Selective Service. All men between the ages of 18 to 25 were eligible to be drafted for a service requirement of 21 months. This was followed by a commitment for either 12 consecutive months of active service or 36 consecutive months of service in the reserves, with a statutory term of military service set at a minimum of five years total. Conscripts could volunteer for military service in the Regular United States Army for a term of four years or the Organized Reserves for a term of six years. Due to deep postwar budget cuts, only 100,000 conscripts were chosen in 1948. In 1950, the number of conscripts was greatly increased to meet the demands of the Korean War (1950–1953).
