Any concerted resistance to lawful military authority.
Mutiny was formerly regarded as a most serious offense, especially aboard ships at sea. Wide disciplinary powers were given the commanding officer, including the power to inflict capital punishment without a court-martial . With the development of radio communications, the threat diminished and harsh punishment was prohibited in the absence of a court-martial.
