During the New Guinea Campaign, Alamo Scout missions normally lasted from one to three days and were mostly reconnaissance and intelligence gathering in nature, but as the Allies advanced into the Philippines the unit's mission expanded dramatically, with some missions lasting two months or longer. Furthermore, the unit assumed a central role in organizing large-scale guerrilla operations, establishing road watch stations, attempting to locate and capture or kill Japanese flag officers, and performing direct action missions, such as the Cabanatuan POW Camp liberation. In January 1945 the scouts were teamed with elements of the 6th Ranger Battalion and Filipino guerrilla units to liberate 513 POWs in a daring night attack. The scouts provided reconnaissance and tactical support for the 6th Ranger Battalion during the raid of the Cabanatuan Prison Camp. The Scouts performed advance reconnaissance of the POW camp prior to the 6th Rangers' Raid on the camp. Prior to the raid, two of the scouts dressed themselves as local Filipino rice farm workers. These two scouts then set up a covert observation post inside a shack in the rice fields that surrounded the POW camp. This hidden observation post was located within a few hundred yards of Japanese Army guard posts at the camp's fence line. The scouts were never discovered by the Japanese during this reconnaissance. The Scouts were credited with the capture of 84 Japanese prisoners of war, and only two Scouts were wounded in the mission.
