Soviet AAA

[kolya1]

Hi,

I've got a quite general question about soviet air defences during WWII...

When reading the german accounts of combats over the Eastern Front, I've always remarked that they spoke of soviet AAA as extremely efficient (although AFAIK the number of claims by soviet AAA was only half or less the claims of fighters...), does anybody knows anything about their numbers, organisation,... ?

AFAIK, the most usual AA guns were 25 mm, 37 mm, 76,2 mm, and 85 mm, even if there were other types in more lmited service (including larger weapons like 90 or 107 mm guns), in addition, there were AA machine-guns, including the famous quadruple 7,62 Maxim, and later in the war the 12.7 DShK heavy MG...

As I understand it, apart from organic AA defences in the ground forces, the anti-aircraft guns were organised in independent divisions, which included both small (25mm and 37mm) and heavy weapons.

Does anybody know how many AA divisions there were in the soviet forces or if these belonged to the PVO (like the air defence guns around soviet-held cities) or were controlled by the ground forces... ?

AFAIK, most of these guns were towed, but does anybody know if there were mobile systems (like truck or track mounted 25mm or 37mm guns...), apart from truck mounted machine-guns ?
