The use of capital punishment by the United States military is a legal penalty in martial criminal justice. Despite its legality, capital punishment has not been imposed by the U.S. military in over sixty years. Reinstatement of the military death penalty The United States Court of Appeals for the Armed Forces ruled in 1983 that the military death penalty was unconstitutional, and after new standards intended to rectify the Armed Forces Court of Appeals' objections, the military death penalty was reinstated by an executive order of President Ronald Reagan the following year. On 28 July 2008, President George W. Bush approved the execution of Former United States Army Private Ronald A. Gray, who had been convicted in April 1988 of multiple murders and rapes. A month later, Secretary of the Army Pete Geren set an execution date of 10 December 2008 and ordered that Gray be put to death by lethal injection at the Federal Correctional Complex, Terre Haute. The military publicly released Gray's execution date on 20 November 2008. On 26 November, however, Gray was granted a stay of execution by U.S. District Judge Richard Rogers of Kansas. In December 2016, a Kansas federal judge, US District Judge J. Thomas Marten, lifted Gray's stay, moving Gray one step closer to becoming the U.S. military's first death sentence carried out since 1961. The U.S. Military currently has four inmates (all men) on death row, the most recent being Nidal Hasan, who murdered 13 people and injured 32 others during the 2009 Fort Hood shooting.
