For most of the Vietnam War, full-time college students and graduate students were able to get a legal deferment from the draft. Since college was expensive, and Black and minority college enrollment was low at the time, this is one of the loopholes that unevenly benefited middle- and upper-class white Americans.
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.
The number of sequence numbers called for induction processing is based on the quota for personnel given by the Department of Defense. This system, based on random selection of birth dates, with the order of priority for reporting assigned in a random manner, is a fair and just method of calling men to serve.
The first date drawn was September 14; all registrants with that birthday were assigned lottery number 1. The next numbers drawn corresponded to April 24, December 30, February 14, October 18, and so forth.
Because the Vietnam War was primarily a ground war, 82 percent of American servicemen who fought in Vietnam were members of the Army and the Marines, and two-thirds of those soldiers were drafted.
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.
Almost all male US citizens and male immigrants, who are 18 through 25, are required to register with Selective Service. It's important to know that even though he is registered, a man will not automatically be inducted into the military.
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.
Most draft-eligible men who avoided conscription took advantage of legal deferments extended to students, fathers, certain professions and people deemed physically or mentally “unfit” for service.
The United States military conscripted approximately 1.9 million service personnel into their ranks over the course of the Vietnam War. Commonly known as the draft, conscription had been conducted in the U.S. through the Selective Service System (SSS) since 1917.
