A few badgers here, but have never heard of them taking on anything. They seem to flee or turn and bury themselves in short order.
I ran into a badger at close range once, at the head of Brownlee Reservoir in NE Oregon. The badger stood it's ground and made some some "mock" charges at me while growling and showing its teeth. I only had a fishing rod with me and backed off to watch it from a distance. I think if I had gotten really close it might have bitten me but I wasn't about to find out.
