After the success of this mission, the invasion of Leyte got underway on 20 October 1944. The 6th Rangers were moved to Tacloban on Leyte, where they were mostly used for patrolling actions. Late in the year, the order came through for the battalion to prepare to take part in the landings in Lingayen Gulf, which were to form the invasion of Luzon. On 1 January 1945, the Rangers were transported by sea from Tacloban to Lingayen Gulf, and were landed on Lingayen Gulf Beach on 10 January 1945. Elements of the battalion were sent to Santiago Island to secure the entrance to the Gulf and prevent the enemy outflanking the landing area.
