The User's Guide to Marine Corps Values is to be used as a tool to help ensure that the values of the Corps continue to be reinforced and sustained in all Marines after being formally instilled in entry level training. This document is a compendium of discussion guides developed and used by Marine Corps formal schools. The guides are part of the formal inculcation of values in young Marines, enlisted and officer, during the entry level training process. This guide is designed to be used as a departure point for discussing the topics as a continuation of the process of sustaining values within the Marine Corps. The User's Guide also serves as a resource for leaders to understand the "talk" and the "walk" expected of them as leaders. New graduates of the Recruit Depots and The Basic School have been exposed to these lessons and expect to arrive at their first duty assignments and MOS schools to find these principles and standards exhibited in the Marines they encounter. Leaders must remember that as long as there is but one Marine junior to them, they are honor bound to uphold the customs and traditions of the Corps and to always "walk the walk and talk the talk." We are the "parents" and "older siblings" of the future leaders of the Marine Corps. America is depending on us to ensure the Marines of tomorrow are ready and worthy of the challenges of this obligation. Teaching, reinforcement, and sustainment of these lessons can take place in the field, garrison, or formal school setting. Instructional methodology and media may vary depending on the environment and location of the instruction. However, environment should not be considered an obstacle to the conduct or quality of theinstruction. This guide has been developed as a generic, universal training tool that is applicable to all Marines regardless of grade. Discussion leaders should include personal experiences that contribute to the development of the particular value or leadership lesson being discussed.
