I think if your clients want to sit on my shoulders and call themselves tall, they have the right to give it a try - but there's no requirement that I enjoy sitting here listening to people lie. You have part of my attention - you have the minimum amount. The rest of my attention is back at the slaughtering pens of Facebook, where my colleagues and I are doing things that no one in this room, including and especially your clients, has the stomach to do.
The Confederates did something like this in the early days of the US Civil War--they painted logs to look like cannons, and they often succeeded in fooling Union surveillance. Why "Quaker" guns?

They look just like real ones: they are easy to transport and quick to deploy. You name it, the Russian army is blowing it up: from pretend tanks to entire radar stations.' But the interesting thing is these decoys are not dumb - actually they appear to be highly advanced for what I thought was a WWII-grade aerial photography countermeasures. Apparently they have heat signatures comparable with the military tech they represent, as well as the same radar signature."
