It turned out the Russians refusal to use artillery on Ukrainian counter-attacks at Izyum had to do with a large set piece artillery barrage the Russians had planned to open their Donbas offensive across the entire front.
The logic chain of that thread fell apart on that point.
It also helped I had been tipped off about coming a coming article saying there was a Russian shortage in 160mm & 240mm mortar ammo because of the heavy use of those calibers in Syrian cities.
The article's...
3/
... publication was put off by the start of the Russian Donbas offensive.
You can now file this under "Trent Telenko can be wrong."
There were additional factors besides those two points that gave me a context to reach that conclusion.

Back in late 2014 I joined a Ukrainian diaspora email list covering the Donbas war. At the time I was studying the 1945 artillery battle at Okinawa.
Weirdness popped out immediately looking at the artillery rocket impact pattern in Kramatorsk
The key to the map
o Green UXO duds,
o Red KIA/WIA
o Blue exploded, no casualties
Most of the rockets overshot the airfield.
Seven out of 41 rockets UXO is an 18% dud rate. 6/
This dud rate is better than the oldest Ex-Soviet stuff seen in Afghanistan (~30%), but not the less than 5% rate of duds seen in older Western ammo.
Acronyms:
UXO - unexploded ordnance
KIA - Killed in action
WIA - Wounded in action.

A shell fuze is an explosive train from smaller to largest of a primer, a detonator and a booster charge meant to set off the main bursting charge of a shell
The photo clip to the right is from a youtube WW2 US Army training film
Note: Fuze =/= Fuse
8/
Generally, as artillery fuzes age, they get less reliable. This is because the chemicals in the Fuze's primer are the most unstable & subject to degrading over time.
Artillery ammunition of all sorts has a life span.
...over time as hot/cold cycles, humidity & trace contamination causes crystallization.
An 18% dud rate on Smerch rockets is a symptom of the aging of the primer in the rocket fuze, AKA a time expired munition.

There were other indications of "time-ex" Russian artillery rocket munitions from the 2015 122mm Grad rocketing of Mariupol.
As rocket propellent ages, it generates marginally & unpredictably less thrust.
Mariupol's 'short' rocketing in the figure right below suggests that
11/
...happened in 2015.
US military practice is to treat solid rocket motors as a 10 year storage item requiring inspect/replace in a missile/rocket midlife depot level refresh
Demilitarizing artillery rockets & shells is an utter pain as it requires EPA regulatory permissions
12/
...for burning the explosives & propellants.
DCMA administers these 'demil' contracts, which is where much of the information I've related on 'time-ex' ammo came from.
Russia's wars in Chechnya & Syria and the 1980's Iraqi purchases of Soviet shells saw large amounts of 13/
Soviet Union's strategic reserve of artillery ammunition used up.
When the US Military overran Iraq in 2003. It found more artillery ammunition, mostly ex-Soviet, than in it's own war reserves.
These Iraqi munitions were destroyed in the US anti-IED campaign of 2004-2007.

Now we get to the 1945 artillery fight at Okinawa.
The radar proximity "VT-Fuze" debuted for the first time in Pacific ground combat at Okinawa.
(I've posted a great deal about Okinawa, see below photos.) 15/
So what is this lack of Russian & Ukrainian airburst fuzing mean?
Good fuzing is expensive, requires high end manufacturing capability & quality control.
Russian artillery simply doesn't have either available.
See this time mortar fuze from Taiwan. 25/
The replacement of chemical percussion, mechanical, and electromechanical fuzing with pure electric-electronic fuzing for superior shell performance is a 21st Century trend Russia is ill prepared to follow.
Taiwan is just one example of this. 26/
This is a Romanian 120mm Mortar with PF-120 proximity fuze ARM shells.
Please carefully note the huge beaten ground caused by the shell fragments in the photo clips & video. 27/
The lack of Russian airburst shelling in Donbas utterly stands out when you look at the lay of the land after repeated shelling over time.
But the best way to upgrade Ukrainian artillery is going to be with NATO & other artillery fuzes to give Ukraine more airburst and other options versus Russia.
And the fuze that will help Ukraine the most is the ATK precision guidance kit fuzes for its incoming NATO 155mm
29/
The PGK turns ordinary 155mm shells into precision guided artillery projectiles (PGAP) at the cost of 10% of maximum range.
You can airlift 40 PGK for the weight of a single Excalibur guided artillery shell. 30/
The PGK requires minimal additional training to properly use and it will vastly reduce the required artillery shell tonnage for the same battlefield impact.
The only reason it cannot be used on current Ukrainian shells is they have the Russian 36mm fuze threads compared 31/
...to the 45mm used on NATO artillery shells.
So the UA would have to take 152mm and 203mm casings and machine out the threads to fit the PGK NATO fuse thread.
Ukraine has a plant in Sumy that manufactures 122mm, 152mm ammo, so this is not an unusual challenge for them.
32/
It is the little things in war that make all the difference.
Things like shell fuzes.
Why we have not seen the Western intelligence notice or Defense Departments & Defense Ministries to go there with upgrading Ukrainian artillery and mortar fuzes is a mystery...

Grok focused on Ukrainian drone capabilities to the exclusion of actual fielded Chinese drone capability and literally eight decades old aviation technology like conformal fuel tanks which have also been applied to cruise missiles in the Chinese technological base for 20 years 2/
The Chinese Sunflower-200 is it's clone of the Iranian Shahed-136. It appeared at Russia's Armiya-2023 show and in 2025 combat in Sudan.
The China Defense website says it has a 3.2-meter length, 2.5-meter wingspan, a flight speed of 160-220 km per hour with a maximum take-off weight of 175 kilograms, a combat payload of 40 kilograms and can fly up to 2000 kilometers. x.com/clashreport/st…

The M109A6 Paladin 155mm/L39 caliber self-propelled gun is the T-62MV obr. 2022 of the artillery world.
The gun is inferior to every other major power's fielded SPG world wide.

The computerized fire direction system of the US Army Artillery is a overly centralized, decades old Star/mini-computer architecture, which has an electromagnetic signature so bright that it can be detected bouncing off the surface of the moon
I cannot begin to tell you all how fishy this passage from that article is:
"In addition to the F-35 production line at Ft. Worth, Texas, the commingling of the two types of bolts was also discovered at the Italian F-35
2/
... Final Assembly and Check-Out (FACO) facility, but not the one in Japan, the DCMA reported."
Spot checking of aircraft production and depot level maintenance facilities fastener bins is a standard operating procedure for DCMA everywhere it has quality personnel.
Why the West, and particularly the US Army, is in deep denial over that reality is rooted in the US Army's denial that the FPV anti-tank drone is replacing the ATGM for cost/performance reasons.
The Ukrainian missile crews salvaging brand new $20K Stugna ATGM to make more FPV drones underlines the battlefield kinematic superiority of multi-copter drones to boost-glide ATGM.
