It is possible that the Corporal in the middle is "Pat" Dunning of the NAMR Signals. However I am sure there are more pointers in the PDF full image to help solve the riddle.(large format at: http://www.nzmr.org/pdf/camp_reinforce.pdf)
This image needed a lot of work and I have tried something different this time - after repairing rips and obvious scrathes and other marks left by the aging process I stripped the photo back and reprocessed it in Duotone like the photographers did in the "olden" days - I hope you like the effect.
