The brigade headquarters were again reactivated on 1 December 2006 at Fort Drum, by reflagging 2nd Brigade, 78th Division (Training Support). It was one of 16 reserve brigades to be activated for the purpose of training. The brigade, which is headquartered at Fort Drum and is subordinate to the First Army Division East, is responsible for early stages of training for other reserve soldiers who have been alerted for deployment. The brigade offers the opportunity for veterans of Operation Iraqi Freedom and Operation Enduring Freedom to use their skills to train new soldiers who will be entering the field of operations in Iraq or Afghanistan. This training includes convoy live-fire training exercises, and techniques in dealing with improvised explosive devices, which are the primary cause of casualties in the operations.
