Novak Djokovic may have topped Andy Murray to claim his fifth Australian Open title over the weekend, but it's who he beat along the way that will really open your eyes.

This video, featuring Djokovic squaring off against a tank, has gone viral and why wouldn't it? It's a frickin' tank playing tennis. Those things sure cover a lot of ground, huh?

Maybe Djokovic will have an easier time at the French Open. Like the play-by-play announcer says, the tank probably can't move so well on clay.
