American soldiers, probably men of 8th Cavalry Regiment, captured by Chinese in their 1st Phase Campaign.
One of the Chinese is apparently armed with a 9mm Sten Mark 2 Machine Carbine, and the other with a Japanese 6.5mmType 38 WWII rifle . The CCF soldier with the Sten has spare magazines on his cartridge webbing, the one with the rifle carries stick grenades.
