WASHINGTON (AP) — Concerned that ethical problems inside the military might run deeper than he realized, Defense Secretary Chuck Hagel ordered service leaders Wednesday to add urgency to their drive to ensure “moral character and moral courage” in a force emerging from more than a decade of war.

Almost a year into his tenure as Pentagon chief, Hagel had been worried by a string of ethics scandals that produced a wave of unwelcome publicity for the military. But in light of new disclosures this week, including the announcement of alleged cheating among senior sailors in the nuclear Navy, Hagel decided to push for a fuller accounting.
