The senior Navy commander in the Pacific has decided not to court-martial Commander Scott Waddle, the captain of the submarine Greeneville, for his actions in the collision that sank a Japanese fishing boat off Hawaii in February, claiming the lives of nine Japanese crew members, including four high school students. According to an unnamed official, the sub commander will be ordered to an admiral’s mast hearing, in which he will be asked to submit a letter resigning from his nearly 20-year Navy career, although he’ll depart with an honorable discharge and his rank and pension intact.
