It's not a simple change though. It's a developing continuum of measures and counter measures.
It's an interesting time, however. Air defence has made the use of close air support by either helicopters or fighters a very questionable practice which seems to be devolving to much longer range shots. Air Defence had primarily been developing over the last half century to meet those threats. There are wide ranging sets of equipment and tactics to deal with those threats and in countering the defences.
UAVs in all their forms, while not new, have only recently been seen as viable and useful tools. They and their countermeasures are in a nascent form and there will be much development happening on both sides. I foresee a fairly lengthy period during which one side or the other - measures or countermeasures - predominates. I'd say that we're in for a bumpy ride and we shouldn't yet throw out some of our old babies with the bathwater. Brute force and dominating ground are still the hallmarks of any army.
