Tanks have rarely been more vulnerable

TANK BATTLES are rare these days. Crews that wish to prove themselves can turn instead to the Tank Biathlon, part of the International Army Games—a sort of Olympics with guns—organised each year by Russia. On September 5th Russian tanks raced and blasted their way to victory over teams from China, Belarus and Azerbaijan.

A century after its debut at the Battle of the Somme, the tank—an armoured vehicle typically equipped with a cannon on a turret—remains the backbone of most armies. The International Institute for Strategic Studies (IISS), a think-tank, counts over 5,000 in Europe, and 54,000 globally.
