Sector One covers a distance of approximately 90 kilometers from Kokkina village on the western coast of Cyprus to the village of Mammari, west of Nicosia.

It has been the responsibility of the Argentinean Contingent since 16 October 1993. The contingent rotates more or less completely every six months. The Military Observer Liaison Officers who liaise daily with military counterparts on the two sides within this region remain in mission for 12-month periods.

Sector One Headquarters and Command Company are located in San Martin Camp, which is near Skouriotissa village. Support Company finds its home at Roca Camp, near Xeros in the north. The two line companies are deployed along four permanently manned patrol bases while also conducting mobile patrols from San Martin and Roca camps.

In addition to its responsibilities in Sector One, the Argentinean Contingent provides personnel to UN Flight unit and contributes to UNFICYP’s Mobile Force Reserve and Headquarters.
