The battalion's employment with the 1st Cavalry Division closely mirrored their use during World War II. One tank company was attached to each cavalry (actually infantry) regiment of the 1st Cavalry Division, with platoons further divvied up one per battalion. Initial missions were route reconnaissance in order to become familiar with the terrain in anticipation of follow-on counterattack or withdrawal orders; and also show of force missions to discourage North Korean probes in the 1st Cavalry sector. Nevertheless, the 1st Cavalry Division was hard pressed by the North Koreans and had to withdraw from key terrain near Taegu between 4–9 September. Stabilizing the front over the next few days, the division and other units went on the offensive on 15 September in support of the Inchon Landings near Seoul.
