The Navy said it has completed its investigation into how sailors ended up in Iranian custody in January. Senior military officials told NBC News that the investigation will recommend disciplinary action.
Ten U.S. sailors spent a night in Iranian custody after their two boats drifted into Tehran's territorial waters. The sailors were videotaped while detained and footage of one sailor appeared to show him apologizing to his Iranian captors.
Senior military officials said several things went wrong and some of the sailors made poor decisions that led to the embarrassing event. One official suggested "more than half" of the detained sailors will face disciplinary action.
"It was a calamity of errors," one U.S. military official said.
