How are mutiny and insubordination treated under military law?

Under military law, mutiny and insubordination are treated as serious offenses that undermine the essential structure of armed forces.

Mutiny

Mutiny is defined as an overt act of defiance or attack against military authority by two or more persons subject to that authority. Historically, it was considered a grave offense, particularly at sea, where commanding officers held broad disciplinary powers—including the authority to impose the death penalty without a court-martial. In modern military codes, however, such summary justice is no longer standard; sentences for mutiny are now typically determined through formal court-martial proceedings. It is distinct from rebellion or revolt, which generally involve broader political objectives.1

Insubordination

Insubordination involves the refusal to obey orders or the act of resisting authority. Because military discipline relies on a clear chain of command, insubordination is viewed as a direct threat to operational integrity. Junior officers or personnel who engage in insubordinate behavior are subject to disciplinary action, which can include being court-martialed for their conduct.23
