ISW suggests that Russian forces might have already taken measures to adapt to the potential Ukrainian ATACMS strikes after Ukraine first used them in October 2023.

The arrival of long-range ATACMS missiles will help Ukrainian forces attack Russian supply lines and airfields in deep rear areas. However, the months of delay in receiving these missiles may have given the Russian military enough time to prepare for the effects of ATACMS, according to the Institute for the Study of War (ISW).
Earlier this week, the United States confirmed it will provide Ukraine with ATACMS long-range missiles as a part of the announced $1 billion package of security aid.
Russia used helicopters a lot to stop Ukrainian assaults in Zaporizhzhia during the summer 2023 counteroffensive, but has not used them as much recently to support its own offensive attacks in eastern Ukraine. Right now, Russia is using a lot of planes to drop glide bombs along the front lines, so withdrawing these aircraft further away probably would have only marginal impacts on their loitering time for conducting glide bomb strikes, as per ISW.
