Books on Soviet air units, campaigns in ww2?

[phuture]

There is obviously a huge amount of books available detailing the Luftwaffe during ww2, but very little regarding the soviet air forces during this time.
Can anyone suggest some (English) books on the soviet air war, preferably concentrating on the units and the campaigns they took part in?

I do have Soviet Air Power in World War 2 which is very good at detailing the hardware, but has little on the campaigns and how the aircraft were used.
There are a few osprey aces books which are interesting, and gems like Attack of the Airacobras: Soviet Aces, American P-39s, and the Air War Against Germany.

I've also noticed a few personal accounts of soviet fighter or bomber pilots coming through as books. Can anyone recommend any of these autobiographies that stand out?
thanks
