So you think the Russians didn’t take out the electricity, roads, rail, TV and radio because they were totally incapable of it.
Riiiiiiight.
When you tell us the Russians have no secret knowledge in reserve whatsoever, this tells everyone on the forum that you have convinced yourself of something you have no way of knowing. Hopefully this isn’t an ongoing habit.
What other explanation is there? It’s the same as the T-14 and Su-57. If you aren’t using an asset in a conflict that is an existential threat to the survival to your regime it doesn’t exist.
