This year marks the 250th anniversary of the founding of the U.S. Marine Corps and Navy. Both were launched in Philadelphia, which will be the site of a big celebration to honor that rich history and its service members. The festivities kick off in October, but we’ll get a sneak peek of the celebration from George S. Leone, president and chair of Homecoming 250 Navy Marine Corps. Mr. Leone will also discussed the fascinating origins of the Navy and Marine Corps.
