Senator, astronaut, Marine—John Glenn's many achievements have distinguished him as a great American leader. He became a Marine following the attack on Pearl Harbor and proved himself a highly skilled combat pilot in WWII and the Korean War.
The U. S. Marine is a professional who stands ready to fight anytime, anywhere, any enemy that the President and Congress may designate and to do so coolly, capably, and in the spirit of professional detachment. He is not trained to hate, nor is he whipped up emotionally for battle or for any other duty the Corps may be called on to perform. Patriotism and professionalism are his only two ‘isms.'
