This great photo shows Father Emil Kapuan during the Korean War. You can learn all about the man Korean POWs called ‘a hero and a saint’ in an article at Kansas.com by Roy Wenzl.

I would have expected to see a M38 windshield in this photo.
Judging by the windshield and the drivers side ax and shovel slots that are just visible, it is a MB or GPW. Korea is interesting in that as to jeeps, the WW2 models, the M38 and late in the war, the M38a1 were all used.
