The best article I’ve seen on Ukraine counter battery fire and the problems they were having was from this August. Relevant section snip at the bottom. I think drones are even more important than counter-battery radar for quick response.
Competent command
Today’s Ukrainian top command structure does not have a specific command and control body responsible exclusively for artillery.
Similarly to the General Staff, neither of the four Ukrainian main operational command headquarters (“North,” “South,” “East,” “West”) have command in charge of artillery.
This is the result of decentralization in the military – the restructuring that was made in an attempt to step away from the over-centralized Soviet military system and towards Western practices.
Before decentralization, top-level structures like army corps command were directly responsible for organizing and running counter-battery warfare. Brigade-level artillery command, in the meantime, was responsible for supporting the infantry on battlefields rather than hunting hostile artillery.
Now, due to lack of centralized command overseeing artillery, there’s inconsistency among the Ukrainian units and they have to fix it, says Oleh Zhdanov, a Kyiv-based retired senior artillery officer.
“Each of the larger front line sectors — like Donbas, Zaporizhzhia, or Kherson — should have at least one or two artillery brigades, that’s four artillery battalions,” Zhdanov said.
“An artillery brigade would be responsible exclusively for counter-battery warfare within the front line’s 100-150-kilometer-long section. It would work as part of the general reconnaissance system. As its forces get fresh data — it immediately goes out to suppress a Russian battery.”
Zhdanov says that each of Ukraine’s operational command headquarters should have a competent artillery department responsible for counter-battery warfare within their sectors.
But this process also needs to be properly organized, with effective communication between the brain and the muscle, to be able to destroy Russia’s most significant advantage over Ukraine.
“The move towards Western methods of working is happening,” said Glen Grant, a retired British Army officer and former adviser to Ukraine’s Ministry of Defense.
“But it is hampered by lack of communications, poor organizational structures, and still the heavy hand of the old concepts. What is missing still for Ukraine is to complete the decentralization of control artillery by improving the radio links, creating, equipping, and training more front line observer teams for battalions,” he said.
Grant continued, saying that there is a vital need to create a separate trade of artillery intelligence and ensure that they operate in all brigades and have direct radio or Wi-Fi links to every possible source of data about enemy artillery.
“Finally, we need a high-flying drone flying back from the enemy lines 50-100 kilometers with sideways-looking sensors to identify artillery positions and movement. Some of this is in place, but a better system will save lives and help win the war.”
