[PAR] [TLE] Conscription in the United States [SEP] Conscription in the United States, commonly known as the draft, has been employed by the federal government of the United States in four conflicts: the American Civil War, World War I, World War II, and the Cold War (including both the Korean and Vietnam Wars).  The third incarnation of the draft came into being in 1940 through the Selective Training and Service Act.  It was the country's first peacetime draft.  From 1940 until 1973, during both peacetime and periods of conflict, men were drafted to fill vacancies in the United States Armed Forces that could not be filled through voluntary means.  The draft was ended when the United States Armed Forces moved to an all-volunteer military force.  However, the Selective Service System remains in place as a contingency plan; all male civilians between the ages of 18 and 25 are required to register so that a draft can be readily resumed if needed.

He was a public opponent of the draft, so he was promptly arrested.  Though his jail time is unknown, it is known that he died at age 34 due to heart problems.
