Estonian intelligence chief Kapo Rosin has an assessment of the Zapad exercise and Russian doctrine in Defense News:
The exercise basically [addressed] two factors. First, how to jam the enemy, which is logical; and second, how to operate [within those] conditions themselves. They of course know that an electronic field is both a challenge for them and a possibility, since Western militaries are very dependent on different electronic communications, reach back and so on.
They know that if they can attack it successfully, then they get the advantage in some fields; and they also know that the NATO is also technically advanced and has its own capabilities. So, the conclusion with Russians is they have to know how to operate under such conditions themselves. You need different skills, procedures and so on to conduct a successful war under those [circumstances]. You have to learn how to command your military with a paper map. So they did that, and I think they are definitely ahead of us [there].
Interesting concept to be ahead by being old fashioned.
