Which supply system is extensively used by Logistics Specialists (LSs)?

The correct answer is RSUPPLY, which stands for Retail Supply. This system is specifically designed for the management of shipboard supply operations and is extensively utilized by Logistics Specialists (LSs) to facilitate the ordering, receipt, storage, and inventory management of supplies onboard naval vessels.

RSUPPLY supports various supply processes, including requisitioning, inventory management, and reporting. It provides a comprehensive solution for managing supply chain processes, ensuring that ships are adequately stocked with the necessary materials to maintain operational readiness.

In contrast, other systems mentioned serve different purposes. NALCOMIS (Naval Aviation Logistics Command Management Information System) is primarily used for aviation logistics. OMMS-NG (Optimized Maintenance Management System Next Generation) is focused on maintenance management rather than supply chain logistics. ATAV (Automated Tool Accountability Voyage) is related to tool accountability and inventory management but is not specifically designed for the broader supply operations that RSUPPLY addresses. Thus, RSUPPLY is the most relevant and extensively used system by LSs for supply management on naval vessels.
