The American Red Cross played a vital role at Camp Adair, providing support and assistance to thousands of soldiers throughout the war. Its main office was located in the post's central area, next to the bus station and behind the bank, making it easily accessible to service members.

The Red Cross helped soldiers facing family hardships or medical emergencies by coordinating emergency communications with families back home. It also sponsored and helped organize dances and recreational activities, particularly in cooperation with the post's service clubs, to boost troop morale.

In addition, the Red Cross provided a variety of supplies and personal items to soldiers. While many services were offered free of charge, some items were sold at modest prices to help support its operations.

The organization also recruited civilian volunteers from nearby communities, including Corvallis, to assist at the station hospital. These volunteers helped care for wounded and recovering soldiers returning from overseas, offering comfort, companionship, and practical assistance during their recovery.

The American Red Cross became an essential part of daily life at Camp Adair, supporting the welfare, morale, and well-being of the men and women who served there.
