<P> If the agency were to mobilize and conduct a draft, a lottery would be held in full view of the public . First, all days of the year are placed into a capsule at random . Second, the numbers 1--365 (1--366 for lotteries held with respect to a leap year) are placed into a second capsule . These two capsules are certified for procedure, sealed in a drum, and stored . </P> <P> In the event of a draft, the drums are taken out of storage and inspected to make sure they have not been tampered with . The lottery then takes place, and each date is paired with a number at random . For example, if January 19 is picked from the "date" capsule and the number 59 picked from the "number" capsule, all men of age 20 born on January 19 will be the 59th group to receive induction notices . This process continues until all dates are matched with a number . </P> <P> Should all dates be used, the Selective Service will first conscript men at the age of 20, then 21, 22, 23, 24, 25, 19, and 18 . Once all dates are paired, the dates will be sent to Selective Service System's Data Management Center . </P> <Table> <Tr> <Th> Class </Th> <Th> Categories (1948--1975) </Th> </Tr> <Tr> <Th> 1 - A </Th> <Td> Available for unrestricted military service . </Td> </Tr> <Tr> <Th> 1 - A-O </Th> <Td> Conscientious objector available for noncombatant military service only . </Td> </Tr> <Tr> <Th> 1 - C </Th> <Td> Member of the Armed Forces of the United States, the National Oceanic and Atmospheric Administration, or the Public Health Service .
