I had a trawl through that link, Mark. A lot of interesting pictures in there. It's gutting to know that there actually were military ones that were destroyed. These are the most military-related ones I could find:
Some sort of Bokharan (sp?) prison guard
Cossack or former cossack?
Gorskiin with Cossack (maybe one of his guards on his photo expedition)
Army officer with uniformed civil servants (I think)
Austro-Hungarian prisoners riding along railway they were used to build
More Austro-Hungarian prisoners. This photo is handy if you're planning to model some of the Austro-Hungarians who fought for the Red Army as it shows how over time, as their clothes wore out, they more and more russian clothing.
Bokharan Palace Guard
Bokharan copper?
It's well worth having a look through those photos though. There is some brilliant inspiration for BoB terrain.
