I agree that currently artillery has more range but the instant they fire counter battery radars can detect their launch points and launch counter battery attacks. This means the artillery and rocket launchers are forced to move after firing and make themselves good targets.IMO these posts both deserve a big BZ. Read them, they are worth it! I also do not think the facts presented and opinions expressed in them are at variance. The first link expresses a personal experience with the limitations of FPV attack drones of the "quadcopter" type. It is a bit dated but does include a section on fiber-optic controlled FPV drones. I think one of its main contributions is attempting to counter the impression that FPV drones mostly "work" and can be counted upon to "complete the mission" almost all of the time. That just isn't so. One wouldn't know that from looking at all the video of successful engagements posted on the internet. Acknowledging the large number of FPV drone successes in a second-strike role on immobilized targets (both human and mechanical) is IMO a very important contribution of this post.
but there is more
For those who may have a serious interest in this subject, here is a more comprehensive view of this issue and well worth the read.

And for those who have a serious interest in this, the author of the above article has a podcast worth checking out: https://podcasts.apple.com/ca/podcast/le...1762473030
GK3's first link is a more analytical look at what drones can and cannot accomplish. This more "high level" look is IMO very valuable. The article also points out the unique factors in the Ukraine war that has led to FPV drones playing roles they for which they are not optimal. The advice to the US Army to formulate a more reasoned approach to the future utilization of drones is IMO on point. Unfortunately the US Army has an absolutely abysmal record in their attempts to develop the "Army of the Future". Many tens of billions has been wasted to little result. There is IMO no reason to believe they will do "better" with drones, unfortunately.
I was particularly gratified that both authors noted the similar capabilities provided by company and battalion level mortars to the current use of FPV drones. I am very on board that idea :-). The ability of mortars to deliver much more explosive on target for less cost is a major advantage. The US has such dedicated assets and they aren't going away. In some cases the mortar carriers used by armored units are quite old and hard to maintain. That needs to be fixed where it exists.
The one factor that both articles mentions is the contribution of drones to situational awareness, target location, and adjusting fires when needed. Integrating this capability into US Army doctrine and making it "work" optimally is IMO the most important immediate task. The Ukraine war initially demonstrated the the delays in the Russian artillery fire direction system were disastrously long. The Russians have attacked that problem with at least uneven results. Since Russian units in general do not have "organic" mortar resources Russia inherently has a "longer" path. The US fire direction loop is much faster (partly because it is much shorter). Drones can improve target acquisition to the point it may stress the system. Lots of scenarios need to be evaluated at the various NTCs to get this right.
Counter-battery radars are a very "interesting" topic. They have been around forever. Most of them in the past were FMCW radars. That made them stand out on any ESM/Elint system. They were trivial to identify. AFAIK these radars are still of that type. LPI counter-battery radars are not (yet) common. Counter-battery radars have one immense problem. In order to respond quickly to an incoming artillery strike they have to be transmitting all the time. They can't "pop up" and then shut down. They have to just sit there and take it. These radars are therefore great targets for destruction via HARM missiles. Worst case they are warned by other command elements that HARMs are flying and they shut down. AARGMs are designed to counter that tactic.
"Back in the day" the Army Security Agency (ASA) also had systems designed to locate counter batter radars and allow the artillery itself to suppress them. Watkins-Johnson built the MLQ-24 back in the mid 70s. https://www.linkedin.com/posts/navy-cryp...3984-SDla/ I also know some of the individuals who worked at the fixed site on the Schneeburg. Note from the second picture the presence of mechanical spinning DF antennas (WJ L-6). Doing DF that way was horribly "slow" but counter-batter radars being on all the time makes it a reasonable tactic. Of course, the MLQ-24 was expected to do many other things where that advantage did not exist. Unfortunately electronic warfare was never a priority to the US Army. The ASA was folded into INSCOM in 1977. That IMO was a mistake. The MLQ-24 had limitations that were budget driven. It did not cover frequencies above 12 GHz. The Soviets by then had many systems that operated in Ku band, 12-18 GHz. "No requirement". Cost too much. The Army was also not interested even in an ALQ-78 style monopulse sum and difference DF system because they couldn't afford the two channel receivers. The Army definitely was not interested in a computer-controlled automatic system even though W-J had such a system available. Too costly. Thus the MLQ-24 was obsolete by design.
The Army was still interested in locating counter-battery radar at the divisional level in the late 1990s. The system contracted to fulfill that requirement is quite familiar to me. The system had so many implementation problems the Army didn't buy it (thank goodness). Devolution in action. It could never pass Op-Eval. It STILL was a single channel system with a spinning DF antenna. It was a computer controlled automatic system and it did reach 18 GHz. It also had a wider IF processing bandwidth. After 20+ years these were some "improvements". To bad it never worked :-).
One historic problem for both the US and the Soviet Union was lack of sufficient numbers of counter-battery radars. Another has been the difficulty in fusing together the data from multiple sites. That data then needs to be used to create appropriate fire-missions. In many cases this process needs to be expedited. The US is pretty good at this, Russia less so. Drones have changed the game considerably because they search behind enemy lines looking for, among other things, artillery. These drones are a threat all the time, not just when a battery is firing. The drone can get an extremely good location fix on its target. Today, that data needs to be expeditiously converted into a fire-mission for the counter-battery battle.
In the future I expect that every battery will have a tethered drone that has the ability to detect counter-battery radars. The drone gets its power up the tether so it can stay aloft indefinitely. The drone will have an interferometer that can produce very high quality Direction of Arrival (DOA) bearings from counter-battery radar emissions. Bearings and Time Difference of Arrival (TDOA) data from multiple drones will be merged to generate an almost immediate firing solution. The life of counter-battery radars is already short on the modern battlefield. It will get shorter.
