Held twice a year, PTSS is a functionally focused program that draws in civilian, law enforcement, and military counterterrorism professionals from around the world and improves their capacity to counter terrorism's regional and transnational implications. It aims to combat terrorism in all of its manifestations: nationally, regionally and globally. Follow this event on Marshall Center Twitter and Facebook with the hashtag: PTSS16_6.
