A lottery drawing – the first since 1942 – was held on December 1, 1969, at Selective Service National Headquarters in Washington, D.C. This event determined the order of call for induction during calendar year 1970; that is, for registrants born between January 1, 1944, and December 31, 1950.
Before the lottery was implemented in the latter part of the Vietnam conflict, there was no system in place to determine order of call besides the fact that men between the ages of 18 and 26 were vulnerable to being drafted. Local boards called men classified 1-A, 18-1/2 through 25 years old, oldest first.
Most of U.S. soldiers drafted during the Vietnam War were men from poor and working-class families. These were young men who were not going get a college deferment, have a political connection, or have a family doctor that could give them a medical deferment.
Certain elected officials, exempt so long as they continue to hold office. Veterans, generally exempt from service in peacetime draft. Immigrants and dual nationals in some cases may be exempt from U.S. military service depending upon their place of residence and country of citizenship.
Around one-third of the military during the Vietnam War were indeed draftees, roughly 1.8 million. Early in the sixties, 23 was the average age of an inductee, but as the war went on, they got younger, falling to almost 20 in 1966.
The various exemptions which draft-eligible men could use to avoid service, such as still being in university education or being medically unfit, were thought to allow better-connected and middle class men to evade the draft more easily than working class or minority men.
A Brief History of the Vietnam Draft. In the early 1960s, nearly all 18 to 26-year-old male U.S. citizens and most noncitizens living were required to register for the draft. Following registration, the U.S. Selective Service (SS) classified registrants as available for service, deferred, or ineligible for service.
~ The largest age group, 33,103 were 18 years old. 12 soldiers on the Wall were 17 years old. ~ 5 soldiers on the Wall were 16 years old.
There were 366 blue plastic capsules containing birth dates placed in a large glass container and drawn by hand to assign order-of-call numbers to all men within the 18-26 age range specified in Selective Service law.
