What does legal power in a military setting derive from?

Legal power in a military setting is fundamentally derived from law and regulations. This encompasses both the applicable domestic laws and military regulations that govern the conduct of armed forces. These laws and regulations provide a framework for action, rights, responsibilities, and accountability within the military structure. They define what is permissible and what is not, guiding decision-making processes and ensuring that operations adhere to legal standards.

In the context of military operations, legal power ensures that actions taken by military personnel are justified and lawful. This could involve compliance with national laws, international humanitarian law, or other legal obligations that may arise during operations. Consequently, understanding the source of legal power is vital for service members, as it shapes their responsibilities and the limits of their authority.

While the authority of commanders is important for operational command and control, it operates within the scope defined by existing laws and regulations. Staff regulations might detail internal procedures but do not grant overarching legal power. International treaties can influence military operations and conduct, but they are part of the broader legal framework rather than the solitary source of legal power. Therefore, the most comprehensive source of legal authority in a military environment stems from law and regulation, making it the correct choice.
