10,000 rounds sounds a bit too generous, are you trying to destroy the army or just kill the leader(s)?
That's also got me thinking down the line of Asimov's psychohistorians. I wonder if enough media has already been moved onto the web that we could harvest enough online data from say, the past 10 years, to feed into a computer model of the world that produces identical results to the historical data. Then if the model is working well, you can start playing what-if games to see what changing one or another factor does to modern life. You could go back further, if you wanted to manually enter all the data, but I doubt you could go back more than a decade or two because there just isn't sufficient data. Dunno.
And then, assuming you have this wonderful computer model, does its existence alter the world that it is modeling? Do you have to keep it a secret so that it's able to model and predict without impacting the world? Imagine if it was just a big Distributed Computing project, and it became well known, commonplace even.
I would guess that the NSA or CIA already has something similar crunching in one of their data centers, but it would be cool to have just for its speculative aspects...
