all you have to do is set up a really large 6-8 lane intersection on the way to the battle. get about 20 or 30 large vehicles, like tractor trailers, and dump trucks, and just keep driving them back and forth through the intersection until their troops come through and all of them get crushed by the large vehicles. if you start to lose the war of attrition, you can always just start randomly crashing the big trucks into their vehicles. chinese people can't see large vehicles somehow. this will be the cheapest, most efficient war ever waged.
