All:
A couple of days ago I read a history of a bookstore, that mentioned one of their prize books. It didn't provide any bibliographic data for the book. Nor any contact information on their website. The bookstore itself is out of business.
The book was originally published in Russian, for the use of officers of the Soviet Army. (Given its content, I'd assume Special Forces, not regular army.) If an officer lost the book, he was instantly executed. After the collapse of the Soviet Union, it was smuggled to the west, where it was translated into English, and sold on the specialty market.
It was written to help officers ensure that their troops survive in urban/semi-urban combat. It lists things such as distance that a match can be seen at night, distance that a cigarette can be seen at night (8 miles), distance that one can hear somebody walking (40 feet). Distance that one can hear a rifle being chambered (120 feet). Distance that one can hear a trigger being pulled (10 feet), etc.
It struck me as a very useful book, for somebody who writes stories about combat, but hasn't been in the military. Or maybe even if they had been in the military. The article said that its most popular audience appeared to members of the officers of the US Marine Corp.
