1953, but in January 1973 Secretary of Defense Melvin Laird announced that no further draft orders would be issued. In March 1973, 1974, and 1975, the Selective Service assigned draft priority numbers for all men born in 1954, 1955, and 1956, in case the draft was extended, but it never was. Command Sergeant Major Jeff Mellinger, believed to be the last drafted enlisted ranked soldier still on active duty, retired in 2011. Chief Warrant Officer 5 Ralph E. Rigby, the last Vietnam War-era drafted soldier of Warrant Officer rank, retired from the army on November 10, 2014, after a 42-year career. December 28, 1972 had been scheduled to be the last day that draftees would be inducted that year. However, President Nixon declared that day a national day of mourning due to the death of former President Truman, and Federal offices were closed. Men scheduled to report that day were never inducted, since the draft was not resumed in 1973. Post-1980 draft registration On July 2, 1980, President Jimmy Carter issued Presidential Proclamation 4771 and re-instated the requirement that young men register with the Selective Service System. At that time, it was required that all males, born on or after January 1, 1960, register with the Selective Service System. Those who were now in this category were male U.S. citizens and male immigrant non-citizens between the ages of 18 and 25; they were required to register within 30 days of their 18th birthday even if they were not actually eligible to join the military. The Selective Service System, still essentially what it was in 1980, describes its mission as "to serve the emergency manpower needs of the Military by conscripting untrained manpower, or personnel with professional health care skills, if directed by Congress and the President in a national crisis". Registration forms are available either online, or at any U.S. Post Office or state motor vehicles office. The Selective Service registration form states that failure to register is a felony punishable by up to five years imprisonment or a $250,000 fine. In practice, though, no one has been prosecuted for failure to comply with draft registration since 1986, in part because prosecutions of draft resisters in the 1980s proved counter-productive for the government, and in part because of the difficulty of proving that noncompliance with the law was "knowing and wilful".
