What is the name of the user's guide for ashore users with Enterprise or DFAS user roles?

The correct choice is the ROM3 User's Guide for Ashore Users. This guide is specifically designed to assist ashore personnel who have roles within the Enterprise or DFAS systems. It provides comprehensive instructions, procedures, and best practices tailored to the specific needs of ashore users, enabling them to utilize the system effectively.

The term "ROM3" refers to a specific version or update of the Retail Operations Management system that is relevant to the Navy's retail operations. Therefore, it is essential that astute users have access to this guide to navigate functionalities, resolve queries, and perform their tasks efficiently as part of their responsibilities in the Navy's retail management.

The other options listed do not match the specific guide required for ashore users nor do they focus on the specific Enterprise or DFAS user roles as adequately as the ROM3 User's Guide.
