Yak-9T - incredible firepower (or maybe incredible tank's lack of armor?)

Do you know the page number or can you narrow it down a bit?

It doesn't matter which model he was speaking of, his claim is that the dive scream was not deliberately generated by a siren, which we all know was indeed a siren.
I don't have the book handy but if you have it in PDF try searching it for references to the siren.
I thought the sirens were installed more by date than by model? Weren't D's also fitted with the siren early on alongside the B's? I know when the D's were converted to G's the sirens were removed as they weren't dive bombers.
