Which document outlines the legal authorities for military actions during operations?

The Uniform Code of Military Justice (UCMJ) is the correct choice because it explicitly establishes the legal framework for military law and governance. It provides the necessary statutes and procedures under which military personnel are held accountable and defines the authority to conduct military operations. The UCMJ encompasses a wide range of regulations regarding conduct, discipline, and the legal obligations of service members, which directly relates to military operations.

The Constitution of the United States, while foundational to the legal framework of the nation and outlining the powers of the military, does not provide specific regulations or authorities for operational conduct in the same way as the UCMJ. The National Security Strategy focuses on broader strategic goals and policies in managing national security but lacks the specific legal authority required for military actions. The Military Operations Manual, while it may guide operational procedures, does not establish the legal authority for military actions, which is fundamentally the domain of the UCMJ.
