The U.S. Navy’s investigation of a January incident in which two U.S. riverine patrol boats were seized by Iranian naval vessels in the Persian Gulf concludes some of the captured American sailors, including the senior officer in charge, violated the military’s code of conduct, which requires detainees to conduct themselves in a manner that avoids discrediting themselves or the U.S. government. Basic military discipline broke down among the U.S. crew as the boats were being seized.

Singled out was the boat captain, the lone officer among the crew of 10 sailors, who agreed to apologize on camera in return for the release of his crew and their boats.
