The Russians control the airspace. So any large movements of vehicles headed into Ukraine's frontlines will be spotted and destroyed.
Those numbers are BS. The Russian ground forces are almost triple that number.
The report above is from 4 years ago when the Russians were still in the middle of beefing up their ground forces.
Even back then they already had more troops than that.
And that is not counting with reserves they could call upon. They massively expanded the size of the ground forces since 2014.
Then you have the Donbass militia also not in those numbers.
Russia has more Ratnik-2 suits in service than the total amount of troops in that list. And not all troops need to use Ratnik-2.
They have like 300,000+ Ratnik-2 suits.
The National Guard is not on those numbers. And Russia has 20,000 Chechens there alone which are not listed.
