“The US Air Force general who once led the air war against ISIS is set to become the Pentagon's top officer. Gen Charles Brown, 60, commanded air operations against ISIS in 2015 as a US-led coalition of dozens of countries sought to push the extremists from their self-proclaimed caliphate in Iraq and Syria. President Joe Biden formally nominated Gen Brown as Chairman of the Joint Chiefs of Staff at a White House ceremony on Thursday, flanked by Vice President Kamala Harris and Defence Secretary Lloyd Austin. ‘Gen Brown is a warfighter who's commanded in Europe, the Middle East and the Indo Pacific,’ Mr Biden said during his remarks.”
