Definition of D&D:
Denial is what it says it is. It's attempts to deny your adversary key information either about your military forces, your leadership, the status of your country, the effect of the adversary's campaign on your country, on its infrastructure, et cetera, et cetera. And there are a lot of ways that that can be done, from the simplest, such as hiding in caves, as we've seen now, to erecting false buildings et cetera to conceal or hide information from intelligence or otherwise.
Deception is slightly different. That's -- if you look at denial as what we would call hiding the real, deception is showing the fake. Okay? That means actually generating, in your classic case, inflatable aircraft or tanks, and again, this goes back to ancient times. Very prolific in World War II. Again, we saw both the Iraqis and the Serbs, who were schooled by the Soviets, fairly advanced deception techniques.
