Using military examples in a list like this is kind of cheating. There's nothing unusual or exotic about fighting tanks with tanks. That's kind of the textbook way to do it, actually. You generally don't send boats after tanks. Or fire for that matter.

Ninjas could fight tanks, but, again, they'd be more effective if armed with tanks themselves.
But one specific case deserves to be mentioned, namely The Great War, World War I, "The War to End All Wars." That last term was actually used by people at the time, with some evidence suggesting it was coined by H.G. Wells. Americans will probably be more familiar with its usage by Woodrow Wilson, who famously used the term when justifying the need for U.S. involvement in the war. The thinking behind it was that once this war was won and the Central Powers (Germany and friends) were defeated, there would be no more potential causes for war left in the world. All the remaining nations would be friendly democracies, with interlinked economies, who'd have no benefit from conflict. This one last war would be it.
"So let's make it count."
