This is what I don't get. Isn't Kyiv a few hour's drive from the border? How can you run out of fuel and food? I guess the only way is if you expected to simply drive directly to a victory march, but surely it's worth being prepared?
Russia’s truck logistic support, which would be crucial in an invasion of Eastern Europe, is limited by the number of trucks and range of operations. It is possible to calculate how far trucks can operate using simple beer math. Assuming the existing road network can support 45 mph speeds, a single truck can make three trips a day at up to a 45-mile range: One hours to load, one hour to drive to the supported unit, one hours to unload, and another hour to return to base. Repeating this cycle three times equals 12 hours total. The rest of the day is dedicated to truck maintenance, meals, refueling, weapons cleaning, and sleeping. Increase the distance to 90 miles, and the truck can make two trips daily. At 180 miles, the same truck is down to one trip a day. These assumptions won’t work in rough terrain or where there is limited/damaged infrastructure. If an army has just enough trucks to sustain itself at a 45-mile distance, then at 90 miles, the throughput will be 33 percent lower. At 180 miles, it will be down by 66 percent. The further you push from supply dumps, the fewer supplies you can replace in a single day.
The resupply line from Belarus to the outskirts of Kyiv is more than 100 miles and over "back roads" - definitely not highway roads.
2) "Driving to Paris" during the cold war was a different time and a different place. And they never attempted it, so you cannot assume it would have been a success.
Their routes into Ukraine in the north and east do not appear to have rail lines for logistics. Note that they have had more success in the south where they likely have a better logistics supply line (more roads, probably better roads, closer to "friendly" territory).
"And here folks is our three liter tank. We like to call it like that because it needs three liters — just to start up."
Why? Because it has a 90hp motor. That just exists to crank the _actual_ main motor at 1000hp+
That day I learned that tanks are veeeeery thirsty beasts.
Finally, a worthy opponent for the average American car :)
Also known as a "Pony" motor. Other heavy equipment such as large Caterpillar D series bulldozers often have these just to start the prime mover.
Also a lot of these machines probably have hellish MPG, as low as 4-10 MPG, even the trucks.
The Pentagon [is reporting](https://news.yahoo.com/russian-troops-surrendering-sabotagin...) some units are self-sabotaging their machinery to avoid fighting.
It would be nice to know how many incidents they have observed.
I've also seen rumblings that the Russian units weren't adequately supplied before setting out, they had been eating through their rations and burning fuel for heat as they sat along the border prior and weren't properly restocked before heading out.
