Watch: Russian military forces take part in huge exercise

Russian President Vladimir Putin on Friday scrambled Russian military forces for a military exercise across the country. The Russian Defense Ministry said that the maneuvers will last until Tuesday and involve around 150,000 troops, nearly 27,000 military vehicles, 414 aircraft and 106 navy ships. It noted that the exercise is intended to train the troops for fending off "terrorist threats" in the country's southwest and prepare for the even bigger "Caucasus-2020" drills later this year.
