Sequence of induction based on age
“The first to receive induction orders are those whose 20th birthday falls during the year of the lottery,” outlines the chain of events for the Selective Service.
Should extra lotteries become necessary, the order would kick off with individuals celebrating their 21st birthday during that year, then climb progressively through ages up to 25. Subsequently, a lottery for those turning 19 would take place, followed finally by 18.5 year-olds.
