If you needed further evidence that the Soviets were more than a little barmy, then here it is. They built a nuclear reactor onto a truck. Thats it, up there. They were used in the more distant corners of the country, presumably because in the more distant corners, fewer people would be irradiated when they used the things.
After the Chernobyl accident, the use of these things was discontinued, but crikey. Imagine seeing one of those things rolling up the main road of your town, village or hamlet. I’d run for my sodding life, wouldn’t you?
