“ If this is true, it means the enemy has an American network-centric battle management system, where all units on the battlefield are net-linked and marked on computers, even at company level, let alone at battalion-regiment level.”
Count on it.
I think a more accurate version would be:
it means the Ukrainians have a Ukrainian developed network-centric battle management system
The Ukrainians have developed a system where local commanders can view drone video feeds and direct their armor, infantry, and mortar support based on live video from above the battlefield.
