Intelligence is one of the most important aspects. Through also we had been at a point where a lot of trope movements are always under watch by satellites and now supplemented by various kinds of drones (some call it the unblinking eye) before. We also have a lot of ways to take advantage of it (long range artillery, big drones, Javelins, small suicide drones, etc.). What changed is not the general capabilities we have nothing I listed (except maybe the small suicide drones) is new. What is new is how we can and in case of Ukrain do combine this weaponry and information systems. So I don't thing any of the tech involved is the defining factor, it's the combination of them in the right strategy.
