The head of a Pentagon unit responsible for accelerating the military's adoption of new technology resigned on Monday, according to four people familiar with the matter, the latest exit of a senior military official whose political views have clashed with those of U.S. President Donald Trump.
Doug Beck, director of the Silicon Valley-based Defense Innovation Unit, told staff in an email that he was stepping down, the people said. He did not provide a reason for his departure in the email, but wrote that working at the DIU was "basically the greatest honor of my life," according to a person with direct knowledge of the email.
