The Neutral Nations Supervisory Commission (NNSC) is the longest running Swiss Armed Forces peacekeeping mission. In 1953, the Federal Council resolved to send approximately 150 Swiss Armed Forces members to Korea. Today five Swiss officers and five Swedish officers are stationed south of the military demarcation line in Panmunjeom. The main duty of the NNSC is to monitor the armistice agreement, which was signed in 1953. This includes inspection of observation and guard posts as well as weapon positions, or the observation of military exercises in the south, and special investigations into suspected ceasefire violations.
