Thank you again:

I will consult the manual for the TT method.

I wish there was an English translation of the book you mentioned [ Combat employment of the anti-air missile forces (based on Vietnam war experiences)]. The link does not work because it seems you copied it from your computer, but in any case since I do not speak Russian, I cannot read the book even if I have it in front of me. Still, I really liked the image posted in this forum.
