Ronald Reagan actually said...

Do your duty. Keep untarnished your honor, and you of the Corps will preserve this country for yourselves, for all of us, for your children,...

You are a prime ingredient that keeps us free, that protects all we cherish and hold dear.

The indispensable factor for protection for all that we hold dear is leadership.

You will be the individuals who most inspire and lead those who are called upon to do the hard and sometimes thankless job.
