On July 1, 2004, the Headquarters once again transitioned in a ceremony marking its designation to Component Command-Land Headquarters, Heidelberg. New structure is currently represented by 15 NATO nations, including its newest members Lithuania and Slovakia. This transformation to CC-Land HQ HD was part of a major NATO restructuring, and realized a fundamental change in headquarters mission and operations, as this headquarters turns its focus from one of six joint sub-regional command headquarters, to assume roles as one of only two land centric headquarters in the NATO command structure designed to provide expeditionary command and control at the operational level of conflict.
