300,000 military men from the Eastern and Central military districts, Northern Navy and Air Forces will take part in the drill, it said.
Some units of the Chinese and Mongolian army are expected to join the manoeuvres at several stages.
More than 1,000 planes, helicopters and UAVs, nearly 36,000 tanks and other armoured vehicles are taking part in the exercises, as well as 80 ships and logistic vessels

If you believe that Russia can successfully field 300,000 personnel from a standing force of a little over 1 million then I have a bridge to sell you. They are notorious for announcing these big exercises that never really happen to the forecast number(s). Their air forces are below 30% fit for deployment/combat and the navy is even a bigger paper tiger.

The Russia economy is a wreck. 142 million people with an economy the size of Kalifornia, that has about 39 million people.
