Reddit reviews Colossus Reborn: The Red Army at War (Modern War Studies (Hardcover))

David Glantz's work on the 1941-1943 era Red Army, Colossus Reborn, contains a section on the development of the artillery branch of the Red Army during that time period. If there are particular figures of note in the Artillery branch, that is where you will find them.

From the German Perspective:

Robert Citino's quadrilogy:

• The German Way of War: From the 30 Years War to the 3rd Reich
  
  
• The Death of the Wehrmacht: The German Campaigns of 1942
  
  
• The Wehrmacht Retreats: Fighting a Lost War, 1943
  
  
• The Wehrmacht's Last Stand: The German Campaigns of 1944-1945
  
  From the American perspective:
  
  Rick Atkinson's Liberation Trilogy:
  
  

1. An Army at Dawn: The War in North Africa, 1942-43
   
   
2. The Day of Battle: The War in Sicily and Italy, 1943-44
   
   
3. The Guns at Last Light: The War in Western Europe, 1944-45
   
   From the Soviet Perspective
   
   Glantz and House's When Titans Clashed is an in depth and authoritative single volume study. If you want to dive into the deep end, expand with:
   
   
4. Stumbling Colossus
   
   
5. Colossus Reborn and it's Companion
   
   
6. Glantz and House's Stalingrad series is a mind-boggling work in and of itself, and constitutes the only Five-Volume trilogy I know of:
   To the Gates of Stalingrad
   Armageddon in Stalingrad
   Endgame at Stalingrad, Book One
   Endgame at Stalingrad, Book Two
   Companion to Endgame at Stalingrad
   
   Glantz has written extensively on the bulk of the war, and his work is quite solid. Punch his name into Amazon for further reading.
   
   There's other books I would recommend, but they're not the sort of flowing and sprawling narrative of the war you seem to be looking for.

Glantz's stuff has been posted already and he's pretty much the one-stop shop for English language discussion of the Great Patriotic War still. Colossus Reborn: The Red Army at War, 1941-1943 is, like it says on the tin, a detailed treatment of the 1941-1943 period. His Stumbling Colossus is also a solid treatment of the lead-up to the war from the Soviet perspective, up through about the end of 1941. It gave me a lot of perspective on Soviet force posture prior to the invasion, and it goes a long way towards explaining why the Red Army performed so poorly in the initial period of the war.

The last two are highly esoteric so I wouldn't recommend starting with them.
