So you like to compete with guns? USPSA, IPSC, IDPA? Perhaps a little 3gun or Cowboy Action? Well these guys compete with tanks lol. There is a Tank Biatholon among other competitions. From this video it looks like helicopter manipulation.

Not sure who came up with this course for the trucks but I imagine this part would suck to drive through.

Then I found this gem, an almost hour long video of the Tank Biathlon where China cheats by cutting off Belarus with their tank. You can see it in the video below at 38 mins into the video.
