Russia has deployed cruise missiles, multiple rocket launchers, tanks and its latest anti-aircraft system at massive military drills in Crimea.

Russia annexed the Crimean peninsula from Ukraine in April 2014 and since then has sent thousands of troops and heavy weaponry there.

The defense ministry invited dozens of journalists Friday to a remote firing range at the Black Sea coast to display elaborate war games which involved paratroopers, tanks, cruise missiles launched from a submarine and the S-400 anti-aircraft missile system.

The drills, which began across southern Russia and Crimea earlier this week and involve over 120,000 troops, are some of the largest exercises Russia has held for years.
