The guy in left wears IMO the pre-war/early war soviet officer’s uniform.
So sorry for my protracted silence, my dear Mr. Tiger 205. As usually, my professional obligations had been very demanding, but finally I do have some spare time on my disposal.
And yes – your observation is absolutely correct. Furthermore – that guy on the left got a rank of Lieutenant General back there in May of 1945. 
thanks,
i was out of the city too…
What can we know about the “major” looking guy on the right?
Many things, my dear Mr. Tiger 205. For example, the fact that he actually served as a Senior Lieutenant of the artillery units in the Red Army.
