Combat Team Conference
The Combat Team Conference (CTC) is a competition of military and law enforcement special operations units. Founded in 1983, it is hosted every four years by the GSG 9 of the German Federal Police in Sankt Augustin in Germany.
The CTC was initiated in 1983 by the former GSG 9 commanders Ulrich Wegener and Uwe Dee in order to improve cooperation among the different units and to encourage the exchange of ideas and experience.
The first CTC in 1983 included 20 different participants which included special response units from the United States, Switzerland, and the Netherlands.
