Vistula-Oder Offensive granular detail required…

I’m currently researching the Vistula-Oder offensive and would like detailed information about:-

· The weather from the 12th January 1945 onwards.
· To identify a Russian unit that fought in Stalingrad, Vistula-Oder offensive and Berlin, preferably all the way to the Fuhrerbunker.
· Day-to-day blow of unit movements and battles fought.

I don’t expect to be spoon fed, just asking for some source materials that might guide me to the answers, half the fun is in doing the research.

I have been using Ospreys Battle of Berlin 1945 End of a Thousand Year Reich which detailed the two offensive but doesn’t go into granular details about unit progression and provides only a very high level overview.
