A very intriguing link courtesy of the Ghost...
The thought experiment started here..."Could I destroy the entire Roman Empire during the reign of Augustus if I traveled back in time with a modern U.S. Marine infantry battalion or MEU?"
And then a fine person took up the task. It blossomed, as such things can, into an amazing collaboration and tale. I predict it on the screen in 2 years or less. The whole thing is here. With a movie poster that made me crack up.
It harkens back to a favorite series of mine, Heroes In Hell. But I suspect most of the contributors are unfamiliar with the stories...nothing new under the sun, perhaps...still, a very interesting little find!
