The Polish zone in Iraq or the South Central / South Center / Central South / Center South zone / sector was created in 2003 when Iraq was divided into four zones. The South Central zone (formerly the Upper South zone) covers the Al-Qādisiyyah Governorate, Karbala Governorate, Babil Governorate and the Wasit Governorate. The region had a population of about 5 million spread over 65,632 km². It was the area of responsibility for Multinational Division Central-South under Polish command.
The Najaf Governorate was passed back to American control in 2004, due to reduction in strength of the forces under Polish command; this reduced the zone to about 3 million of population spread over 28,655 km². Major cities in the Polish zone include Diwaniyah, Kut, Hillah, and Karbala and Najaf.
The strength of the Polish forces have decreased from 2,500 (2003) to 900 (2007); the Multinational Division Central-South numbers about 2,000 troops. Polish casualties number 25. Casualties of the entire division are 65.
