A small group of top Mexican military and intelligence officials also visited the command's targeting center at the Balad air base in Iraq before the U.S. troop withdrawal in 2011, a former U.S. official said.
U.S. officials stress that sharing this expertise does not mean U.S. special operations teams will be conducting raids against targets in Mexico, nor will they be entering the country with their own weapons. Mexico forbids U.S. military or law enforcement officers from carrying guns inside their borders, with few exceptions, though American commandos have conducted training missions in the past, two current and one former U.S. military official said. They were speaking on condition of anonymity because they were not authorized to discuss the sensitive missions.
