Which of the following is NOT a source of military law?

Military law is derived from various sources that govern the conduct of military personnel and operations. The correct answer indicates that presidential executive orders are not classified as a primary source of military law but rather can be considered a broader tool used by the President to direct specific actions or policies within the military framework, which may not directly constitute military law itself.

Military regulations consist of formal rules established by military departments that provide guidance on the operation of military functions and the behavior of service members. Statutory law refers to laws passed by legislative bodies, including those that specifically address military matters, and case law is established through judicial decisions in courts, which interpret and apply existing laws to specific situations.

While presidential executive orders can influence military operations and conduct, they do not fall into the category of military law in the same way that regulations, statutory laws, and case laws do, which are foundational to military legal structure.
