This is a thread that will explain the implied poor Russian Army truck maintenance practices based on this photo of a Pantsir-S1 wheeled gun-missile system's right rear pair of tires below & the operational implications during the Ukrainian mud season.🧵
1/
For the sin of being the new guy, I was the DCMA quality auditor in charge of the US Army's FMTV "vehicle exercise program" at the contractor manufacturing them from the Mid-1990's to the mid-2000's Then we got more new guys.
Short form: Military trucks need to be...

...turned over and moved once a month for preventative maintenance reasons.
In particular you want to exercise the central tire air inflation system (CTIS) to see if lines have leaks or had insect/vermin nests blocking the system.

One of the biggest reasons for the repositioning, per TACOM logistic Representatives, was that direct sunlight ages truck tires.
The repositioning of Trucks in close parking prevents a lot of this sun rotting and cycling the CTIS keeps the tire sidewalls supple.
4/
When you leave military truck tires in one place for months on end. The side walls get rotted/brittle such that using low tire pressure setting for any appreciable distance will cause the tires to fail catastrophically via rips.
There is a huge operational level implication in this. If the Russian Army was too corrupt to exercise a Pantsir-S1. They were too corrupt to exercise the trucks & wheeled AFV's now in Ukraine.
The Russians simply cannot risk them off road during the Rasputitsa/Mud season 7/
And there is photographic evidence of this.
There are 60(+) Russian army trucks crowded & parked on this raised road bed to avoid the fate of the mud-bogged Pantsir-S1.

Given the demonstrated levels of corruption in truck maintenance. There is no way in h--l that there are enough tires in the Russian army logistical system.
So their wheeled AFV/truck park is as road bound as Russian Army columns were in the 1st Russo-Finnish War. 9/
What that means is that as long as and where ever the Spring Rasputitsa is happening. The Russian Army attack front is three wheeled AFV's wide.
When the Ukrainians can block the road with ATGM destroyed vehicles. They can move down either side of the road like Fins in 1939 10/
...destroying Russian truck columns.
The Crimea is a desert and the South Ukrainian coastal areas are dryer. So we are not seeing this there.
But elsewhere the Russians have a huge problem for the next 4-to-6 weeks.

The first was the UK's Operation Outward. It was noticed after a windstorm during 1940's Battle of Britain that barrage balloons dragging severed cables under them caused shorts on power lines, damaging the power grid in occupied Europe.
This would be the 2nd reported downing of a Tu-22M by an S-200. The earlier Tu-22M being in December 2023.
It looks like these Tu-22M are still using Soviet era EW suites which were not geared against the S-200 C-Band, 100 KW, 5N62 Square Pair FMCW tracker/illuminator. 2/
Between ~1996 and 2005, most FMTV trucks accepted by DCMA for the US Army had my signature on the truck property forms along with my DSN phone number.
I got three or four calls in Sealy Texas from NCO's in Iraq trying to score ballistic composite glass armor because they stopped these EFP attacks⬇️
1/
DCMA Sealy was getting photos from contractor relatives of bombed FMTV's with sheet metal armor and receiving IED damaged trucks to get rebuilt.
You could tell the blast damage from how the windows were missing and the roofs were bowed at the top.

When you pulled out the stowage boxes in the cabs there were usually spent 5.56mm or 7.62mm brass casings...
Or SAM hunters can use a weather balloons with a set of commercial off the shelf ELINT and thermal imaging sensors - connected via a smartphone - hanging underneath to listen for radars and look for SAM missile launches 24/7.
The world has changed.
(I wonder if the Houthi are doing this balloon surveillance trick to the Western merchantmen?🤔)
The thing that has deeply bothered me about this RuAF Tsar-shed tank with jammer and the earlier "Pallet Jammer" tank is the complete lack in any public analysis of the mention of Electromagnetic compatibility (EMC).
You can't throw radio-electronic systems together and expect them to work properly.
EMC🧵
1/
I have spend too many hours on too many days outside an Anechoic RF chamber with EMC test procedures and fiddly oscilloscopes to miss the fact that the drone jamming systems the Russians have deployed on tanks in Ukraine are missing such testing.
Corrugated steel doesn't an effective R/F ground plane make.🙄
Ukrainian reports claim four FPV drones were stopped by the "Pallet Jammer" tank while the fifth managed to immobilize the tank for later capture and analysis.
There were some claims that this 5th drone was immune from jamming
