Later, the United States commander in Afghanistan, General John F. Campbell, said the airstrike was requested by Afghan forces who had come under Taliban fire. Campbell said the attack was "a mistake", and "We would never intentionally target a protected medical facility."[1][12] Campbell said the airstrike was a US decision, made in the US chain of command. The USCENTCOM 15-6 report stated that General Campbell's own lack of strategic guidance and dissemination of certain Rules of Engagement were major contributing factors that led to the command and control breakdown prior to the airstrike.[13] Anonymous sources alleged that cockpit recordings showed the AC-130 crew questioned the strike's legality.[4]
