About: Nuclear command and control

Nuclear command and control (NC2) is the command and control of nuclear weapons. The U. S. military's Nuclear Matters Handbook 2015 defined it as the "activities, processes, and procedures performed by appropriate military commanders and support personnel that, through the chain of command, allow for senior-level decisions on nuclear weapons employment." The current Nuclear Matters Handbook 2020 [Revised] defines it as "the exercise of authority and direction, through established command lines, over nuclear weapon operations by the President as the chief executive and head of state."
