OK, we're all used to the "war/oil" thing. And from time to time (depending on the price of oil) we hear about the limited oil reserves etc. So let's assume for a minute that we run out of oil somewhere in the not so far future. What would be the nature of warfare after the "last drop of oil"? (BTW isn't it interesting that there is no reference to "post oil" combat systems/vehicles, even as "brainstorming" projects, at least I've not stumbled on anything similar on the net, maybe the oil reserves aren't so limited after all!
