Gen. Bradley addressed the new second lieutenants saying:

“So, as you gentlemen go out and continue your military career, remember you are going to assume more and more responsibility. It is an honor and privilege to serve our great country. Continue to learn how to be of great service to that country and remember you are leading men, American men who are really something special. Understand them and be loyal to them while, at the same time, you are being loyal to your superiors, your mission and your country.”
