Summary:
Russian Ministry of Defense started organizing a tank-based competition of crew and gunnery tank skills. So far, it’s only a Russian event, but by 2014, NATO and US Army are expected to join.
The basic idea behind the tank contest is simple and repeats the rules of the classic biathlon: cover about 20km in shortest time while successfully hitting your targets.
More details and pictures in the linked article. However, one thing is very interesting: the official MOD video (check the music, familiar?)
