Former Acting Secretary of the Navy Thomas Modly wrote Wednesday about the lessons he learned while leading the service, which included checking your anger and avoiding profanity.

Modly resigned under fire last April after removing the commanding officer of an aircraft carrier stricken by COVID-19 and flying to Guam to where he trashed that officer to his crew in a profanity-laced speech. In his new column, published in the U.S. Naval Institute’s magazine, Thomas Modly admitted that he made mistakes as the head of the Navy.

“Everyone makes mistakes. Everyone,” Modly wrote in the article. “In times of high tension and stress — times like the current COVID-19 pandemic — fear often accentuates mistakes and increases the misinterpretations of facts surrounding them.”

In early April, Thomas Modly publicly fired Capt. Brett Crozier, the USS Theodore Roosevelt’s commanding officer, after a letter the captain had written warning about a worsening coronavirus outbreak aboard the carrier leaked to the media. Days later, Modly flew out to Guam, where the carrier had been sidelined by the outbreak, to talk to the crew.
