Watch Russian military tanks maneuvering as if they were dancing, as they perform in a precision drill. In the opening movements, the T-80 and T-90A tanks maneuver to techno music. There is a brief tango interlude. For the classical portion, the Russian arms company enlisted a ballet director from the Bolshoi Theater, Andrei Melanin. He choreographed the machines, which range in weight from about 42 to 47 tons based on their configuration, to excerpts from “Carmen,” the opera by Georges Bizet.

The Russian tanker crews seem to coax their machines into delicate, even coquettish advances on other tanks. They pair up and separate, lower their guns like lances and charge at one another. At one point, two tanks twirl in a creaky, diesel-smoke-belching embrace.

The tanks, and at times a self-propelled artillery piece, are maneuvering on a square 30 yards by 30 yards at an airfield used for military exhibits in Zhukov.
