WASHINGTON, D.C. (July 30, 2006) -- Jimmy McCain, 18, the youngest son of U.S. Sen. John McCain has enlisted as a Marine and will soon report for boot camp in San Diego, Calif., Time Magazine reported on July 29.

"I'm obviously very proud of my son," Sen. McCain told Time, "but also understandably a little nervous."

The younger McCain comes from a long-line of family members who have distinguished themselves in combat and the naval services.

His great-grandfather was an admiral who commanded naval forces during World War II in the Pacific and was present for the Japanese surrender aboard the U.S.S. Missouri. His grandfather rose to become an admiral and commanded all U.S. forces in the Pacific during the Vietnam War.

His father was a storied Navy fighter pilot, shot down over Vietnam and held as a prisoner of war for over five years. His older brother Jack McCain, 20, recently finished his plebe year at the U.S. Naval Academy at Annapolis, Md.

Jimmy McCain will be the first McCain to enlist and don a Marine uniform.

He is perhaps following his own father's exhortations for Americans to strive to be of greater service to their communities and country.

"Glory belongs to the act of being constant to something greater than yourself," said Sen. McCain some years ago, "to a cause, to your principles, to the people on whom you rely and who rely on you in return."
