A more thorough explanation:

The Uniform Code of Military Justice (UCMJ) is a set of federal laws that govern the behavior and legal proceedings for members of the United States military. It outlines the rules and regulations that military personnel must follow and the consequences for violating them.

For example, the UCMJ prohibits military personnel from engaging in certain behaviors such as fraternization, hazing, and sexual harassment. If a service member is found guilty of violating these rules, they may face disciplinary action such as demotion, loss of pay, or even imprisonment.

The UCMJ also outlines the legal procedures for military trials, including the rights of the accused and the responsibilities of the prosecution. This ensures that military personnel are held accountable for their actions while also protecting their rights.
