A Russian T-90AM tank firing its 125mm cannon as it flies off a ramp. Even after the fall of the Soviet Union, Russia still has more tanks than any other country in the world: 15,500. China and the USA follow with 9,150 and 8,325 respectively. Russia is now conducting its annual world tank championship.
I would have thought that there is a finite amount of engineering that could go into a football / soccer ball, but the Nike T90 has proven me wrong.
