Russia's military might was on full display Wednesday as the country held its annual Victory Day parade in Moscow's Red Square.

Vladimir Putin, who recently began his fourth term as Russian president, had pride of place at the display, which featured thousands of soldiers, scores of armored vehicles, and new hi-tech additions to the Russian forces.

Victory Day is held every year to celebrate the Soviet Red Army's role in defeating Nazi Germany. As such, a spattering of vintage technology also made an appearance.

Highlights included the parade debuts of the Su-57 stealth jet, as well as the Uran-9 "robotank."
