Which of the following units is specifically tasked with personnel accountability?

The Human Resources Unit is specifically tasked with personnel accountability as its primary function is to manage and oversee the personnel aspects of military operations. This includes tracking the status, location, and overall welfare of troops, ensuring that accurate records are maintained, and facilitating the timely dissemination of this information to command elements. Personnel accountability is critical to mission success, safety, and operational readiness, making the Human Resources Unit essential in maintaining a clear understanding of who is present and available for duty.

The other units listed have distinct focuses that do not primarily involve personnel accountability. The Logistics Support Unit concentrates on the supply chain and support operations for resources, equipment, and logistics management. The Operations Control Unit is responsible for planning and coordinating missions, overseeing operational execution rather than personnel management. Lastly, the Military Police Unit focuses on law enforcement and security operations within the military context, which is unrelated to tracking personnel. Therefore, the Human Resources Unit stands out as the clear choice for the responsibility of personnel accountability.
