However, I did serve decades ago in the US Army (in an armored unit), and I stay current with things that are of interest to me, insofar as I can as a civilian. I am also active politically, and I voraciously read history and tech books (as well as SF/fantasy) and I'm pretty skilled at information research (which I first learned to do for science fair projects in high school, then later in college when I was majoring in physics). You'd be amazed at what you can learn on your own when you put your mind to it. The hard data on nukes I pulled from the web in a few seconds while I was replying to you. The rest was from my memory.

Most of the information you can find about operational limits and theoretical analysis of nuclear payload, distance, and detonation time along with hypothetical responses can be found all across the 'net. It's major currency for conspiritorial nuts.
