COMMITMENT is the spirit of determination and dedication found in Marines. It leads to the highest order of discipline for individuals and units. It is the ingredient that enables 24-hour-a-day dedication to the Corps and country. It inspires the unrelenting determination to achieve a standard of excellence in every endeavor.
Total dedication to Corps and Country. Gung-ho Marine teamwork. All for one, one for all. By whatever name or cliche, commitment is a combination of (1) selfless determination and (2) a relentless dedication to excellence. Marines never give up, never give in, never willingly accept second best. Excellence is always the goal. And, when their active duty days are over, Marines remain reserve Marines, retired Marines, or Marine veterans. There is no such thing as an ex-Marine or former-Marine. Once a Marine, always a Marine. Commitment never dies. When times are tuff, you are tired and you don’t think you can continue, that’s when commitment prevails, you get a second wind and you overcome your situation as a Marine.
The truth lies in the individual Marine. He (or she) did not join the Marines. Roughly 40,000 try each year. Those who survive the crucible of Marine basic training have been sculpted in mind and body. They have become Marines.
Once he has earned the title and entered the Brotherhood of Marines, a new warrior must draw upon the legacy of his Corps. Therein lies his strength. In return, the strength of the Corps lies in the individual Marine. The character (often defined as "what you are in the dark") of these warriors is defined by the three constant Corps Values: honor, courage, and commitment.
The three Corps Values: honor, courage, commitment. They make up the bedrock of the character of each individual Marine. They are the foundation of his Corps. These three values, handed down from generation to generation, have made U.S. Marines the Warrior Elite. The U.S. Marine Corps: the most respected and revered fighting force on earth.
