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...
2/
...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.
8/
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.

...procurement programs and the MLRS artillery rocket system in the late 1970's-to-early 1980's.
The post 1973 Arab Israeli War US Army understood the idea of "the logistical costs of a stowed kill." 2/
The US Army kept the 105mm on the M1 in production so long because the depleted uranium (DU) 105mm "Long Rod" APFSDS could kill a early T-72 and you could carry 55 rounds versus 40 rounds for a 120mm gun firing a tungsten APDS or early DU APFSDS round.
What killed Imperial Japanese soldiers in WW2 "without a mark" inside bunkers was carbon monoxide poisoning, not a lack of O2.
Once you get enough CO in the lungs on the O2 chemical bonds.
No further O2 can get into the bloodstream and you suffocate.

I ran across that fact in a trip report of a US Army Chemical Warfare Service (CWS) medical doctor sent to Leyte to take blood samples from IJA corpses that died from flame weapons.
It didn't work out and the CWS used goats in bunkers hit with flamethrower weapons to get the CO poisoning medical data.
Any trench w/o overhead cover and any passage or firing slit that is big enough to shoot a crew served heavy weapon or vehicle out of is also big enough for a FPV drone spewing thermite to fly into.
2/
Every field fortification manual ever written by every military in the world is obsolete and will have to be re-written with an eye to placing curtains, nets or wire screens across firing slits and doors to keep out small drones.
The "missile" impacts have the classic artillery rocket impact ellipse with strikes being on the line of flight axis having more dispersal (long/short) that left or right of it.
One of the spaces @secretsqrl123 had with @RyanO_ChosenCoy present. He made clear Ukrainian FPV drones based on Hollywood camera multi-copters have a 50 km one way range.
The other issue is the disintermediation of drones from platforms. 1/
"Disintermediation" means any shipping container or flat space on a vessel/vehicle works as a launcher.
A ISO container with 126 drones can be stacked on a 24 X 24 top level of a Chinese MGX-24 container ship and lob 72,576 drones in a simultaneous wave 50 km or more.
2/
Another thing that works are simple racks in cargo aircraft, helicopters or boats.
The Russians are using simple racks in the Mi-8 to hold FPV drones in large numbers to engage Ukrainian boat drones or special forces craft with MANPADS or FPV's.
Missiles are structurally strong nose to tail because, rocket acceleration. Side to side missile structure is as weak/light as possible for performance reasons.
Railway gondola cars moving missiles like this rattles them side to side like beans in a maraca.😱
