KILIS, TURKEY - MARCH 02: A Turkish soldier from the 1st Border Regiment Command looks out over the border wall to Syria during alert drills at a military outpost on the Turkey/Syria border on March 2, 2017 in Kilis, Turkey.  The military exercises were held to display the new border wall and new security measures such as thermal scanning and patrols by the new Tactical Armoured Reconnaissance vehicles (Kobra-2) that are being used to tighten Turkey's border. The government announced this week that more than half of the 511-kilometer wall has been completed.  (Photo by Chris McGrath/Getty Images)
