Final answer:
The three sources of basic disciplinary laws for the U.S. Navy are constitutional directives for maintaining a Navy and regulating forces, provisions for calling forth the Militia, and statutes such as the UCMJ.
Step-by-step explanation:
The three sources that contain the basic disciplinary laws for the U.S. Navy are:
- To provide and maintain a Navy; this is a constitutional directive that gives Congress the power to establish and sustain the Navy.
- To make Rules for the Government and Regulation of the land and naval Forces; this is another constitutional provision that empowers Congress to regulate and set standards for the United States' naval and land forces.
- To provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions; while this specifically pertains to the Militia, it indicates the broader framework of military law and the role of armed forces in national defense.
In addition to the Constitution, the UCMJ (Uniform Code of Military Justice) serves as a key source of military law, and the Manual for Courts-Martial elaborates on the legal procedures for military justice. The role of the Commander in Chief, as stipulated in Article II of the Constitution, and the judicial powers in Article III, further shape the legal landscape for the armed forces, including the U.S. Navy.
