Which of the following is primarily designed to protect the rights of victims during investigations?

The correct choice is the Department of Defense Directive 1030.1 (DODD 1030.1), as it specifically outlines policies and procedures aimed at protecting the rights of victims within the military justice system during investigations. This directive establishes the framework for ensuring victims are treated with fairness, dignity, and respect, and it emphasizes the importance of informing them of their rights and the services available to them.

DODD 1030.1 is important because it mandates support services for victims, including access to information about the status of their case and assistance throughout the judicial process. This proactive approach is crucial for fostering an environment where victims feel supported and empowered, which aligns with the overall goals of the military justice system to deliver equitable treatment to all parties involved.

The other options, while relevant to military procedures and the legal framework, do not primarily focus on victim rights protection during investigations in the same comprehensive manner as DODD 1030.1 does. Article 31(b) relates to rights of the accused regarding self-incrimination, DA FORM 3881 is a form used for reporting sexual assault, and the Uniform Code of Military Justice (UCMJ) establishes the legal framework for military justice but does not specifically emphasize victim rights.
