What reform did the selective service system put in place toward the end of the Vietnam war?

Toward the end of the Vietnam War, the Selective Service System implemented a lottery system for draft selection, introduced in 1969. This reform aimed to make the draft process more equitable by randomly selecting individuals based on their birth dates, rather than relying on the previous system that often disproportionately affected lower-income and minority populations. This change was part of broader efforts to address public discontent with the draft and the war itself.
