According to DOD guidelines, which instruction mandates the maintenance of full accountability for all detainees?

The directive that mandates the maintenance of full accountability for all detainees is DODD 2310.01E, known as the Department of Defense Detainee Program. This instruction outlines the overarching policies and responsibilities regarding the treatment, detention, and care of individuals held by the Department of Defense. It emphasizes the importance of accountability and establishes procedures that ensure that all detainees are properly documented and that their rights are upheld in accordance with applicable laws and regulations.

By providing clear guidance on the accountability of detainees, this directive plays a crucial role in maintaining ethical standards and operational integrity within the DOD's detainee operations. It ensures that all personnel are trained and aware of their responsibilities related to the treatment and oversight of detainees, which is vital for compliance with international laws and agreements.

In contrast, the other directives mentioned focus on different aspects related to detainee operations, such as operational procedures, treaties and agreements, or conduct and discipline, but do not specifically center on the accountability of detainees like DODD 2310.01E does.
