I have heard on podcasts that the way the Russians make plans for the Ukraine war is like this:

There are rooms in the kremlin with no electronics. In these rooms there are paper maps and typewriters and printed reports. People look at the maps and printed paper reports and make plans. Orders are typed up on the typewriters Then trusted couriers take those orders by hand to the front line commanders.

I've also heard on podcasts there is a weekly flight back and forth between Beijing and Moscow. On that flight are a Russian military officer and Chinese military officer. Their sole job is to carry handwritten notes back and forth between Putin and Xi Jinping. There is one of each so they can watch each other.

All of this ensures that there is nothing for the west to hack at "the Russian Pentagon".

The west may have to adopt tactics like these for our plans to stay secret.
