unfortunately these are russian soldier. let me prove it. First they are not Turkish soldiers. it doesnt need any source every Turkish person knows that the Turkis army started using these round hats (see... the guy on the left is wearing one of these)long after the Turkish republic. These hats were not used by germans also. if you are not satisfied check these link to see Turkis army clothes.[] [] []. for german army:[] So who were wearing that kind of uniforms? Fellow Russians ofcourse   [], [][](page 3)
And take a close look at the bayonets and rifles. See anything? the same bayonets and rifles. 
Finally; the resolution is not good still if you take a close look you will see that some dead guys (if not all) are cicumcised. So Eupator I am not talking out of my A... You are withnessing a shameless act here. Putting pictures where muslims were killed by Russian-Armenian army and presenting it as a genocide proof. even writing Turkish soldiers proudly posing with bodies of their Christian victims. To these, the "Christians were like animals to be hunted.". Simply nausating.  

FYI: I say Russin-armenian army because American newspapers of that time were also using that description.
