KILIS, TURKEY - MARCH 02:  The border wall is seen from a 1st Border Regiment Command outpost during military drills 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)
