Looks good. Maybe split off 2 Tunguskas from each battery, to form two additional batteries of 4, to protect sites H and I? The systems could remain cold, and be used to take out incoming missiles, and even bombs.
It called Gazetchik-E (or 34Ya6E) and it is usually hoked up with Gamma DE radar, so as soon it detect Anti radar missile, it shot down radar it defend and start to popping up decoys as crazy.Russia also has some kind of electronic equipment ( I forgot its name) that send out decoy signals to confuse/fool incoming anti-radiation or cruise missiles. A few of those equipment to protect anti-aircraft missile systems would also be needed.
