What is the primary record-keeping system for tracking Class V items?

The primary record-keeping system for tracking Class V items is the supply management system or property book. This system is specifically designed to manage and account for property and inventory, ensuring that all Class V items, which typically include munitions and explosives, are tracked accurately throughout their lifecycle.

Using the supply management system allows for systematic recording of item quantities, locations, and statuses, which is crucial for efficient logistical support and operational readiness. This ensures that all personnel involved in handling Class V items can quickly access up-to-date information and make informed decisions regarding inventory management, issuance, and turn-in procedures.

While other systems like the financial management system and logistics command system support various aspects of military operations, they do not specifically focus on the detailed tracking and accounting of Class V items. The personnel management system is primarily concerned with human resources and does not deal with inventory management, further highlighting why the supply management system is the correct choice.
