The 2006 - 07 BCT reorganization disbanded E Troop altogether and converted the 3rd Battalion " Warrior " , 124th Infantry into what is the 1st Squadron , 153rd Cavalry . Though E Troop and 1st Squadron share the same coat of arms , 1 - 153 Cavalry was constituted entirely from the infantrymen of 3 - 124 Infantry and so continue the 3rd Battalion ' s lineage .

Companies of the battalion were attached to 108th Air Defense Artillery Brigade , 3rd Infantry Division , and 1st Marine Division during the invasion . In 2004 when 3rd ID left , 3 - 124 Infantry was attached to 1st Armored Division . The battalion was assigned to downtown Baghdad . Organization ( 1968 - 2007 ) . Three years after the cavalry transformation the squadron was mobilized and deployed with the 53rd Infantry Brigade Combat Team in support of Operations Iraqi Freedom and New Dawn .
