A more thorough explanation:

Naval law is a set of rules and regulations that govern the behavior and actions of naval forces. It is similar to the Code of Military Justice, which applies to all branches of the military.

For example, naval law may dictate how sailors are expected to behave while on duty, how they should handle classified information, and what punishments they may face for breaking the rules. It also covers issues such as maritime law, which governs the use of the oceans and other bodies of water.

One example of naval law in action is the Uniform Code of Military Justice (UCMJ), which is a set of laws that apply to all members of the military, including those in the Navy. The UCMJ covers a wide range of offenses, from minor infractions like being late for duty to serious crimes like desertion or mutiny.
