Counter-battery fire really only applies to gun-based artillery, since it has nearby ammo (or stored ammunition on the vehicle) and the counter-battery radar is sited to detect and calculate the ballistic trajectory instantly.

When it comes to missile (whether drone, cruise missiles, or ballistic missiles), it's much more difficult. The US had a hard time countering the SCUD missiles in 1991. And that was with a huge military, with the best ISR the world has ever seen. A 6-pack of Shaheds can be launched from a trailer that looks all the world like a normal flatbed style semi. A cruise missile can be fired and navigate a course that obfuscates its launch point. Ballistic missiles can fire, then drive away to hide in a city.

The only way to win this fight is to blockade the country from receiving shipments from Iran. Air blockade and naval blockade, combined with strikes to hit known depots etc. This is called war. Not a presence mission, not a "response," but the literal definition of war. The US has no stomach for this entanglement, and hopes that the problem goes away. It won't, but the pain level is relatively low, and the USN is getting some great practice in fighting a LIC in the littoral regions.
