Great read on where Russia could run into trouble and reports have already shown that Russia is losing large amounts of truck supply convoys on the back of their invasion.

Russian army logistics forces are not designed for a large-scale ground offensive far from their railroads. Inside maneuver units, Russian sustainment units are a size lower than their Western counterparts. Only brigades have an equivalent logistics capability, but it’s not an exact comparison. Russian formations have only three-quarters the number of combat vehicles as their U.S. counterparts but almost three times as much artillery.

The reason Russia is unique in having railroad brigades is that logistically, Russian forces are tied to railroad from factory to army depot and to combined arms army and, where possible, to the division/brigade level. No other European nation uses railroads to the extent that the Russian army does. Part of the reason is that Russia is so vast — over 6,000 miles from one end to the other. The rub is that Russian railroads are a wider gauge than the rest of Europe. Only former Soviet nations and Finland still use the Russian standard — this includes the Baltic states. There are several railheads prior to Baltic capitals, but it will still take several days to reach and establish railhead operations. Forward railhead operations are more than just cross-loading cargo from train onto truck. It involves receiving and sorting cargo, repackaging for specific units, and storing excess on the ground. Due to the hazardous nature of military cargo, the ground needs to be prepared so that cargo can be stored in safe, distributed environments. This process can take one to three days. The site also needs to be outside the range of enemy artillery and secured from partisans. A single lucky shell or an rocket propelled grenade can result in a major explosion and have a disproportionate effect on the tempo of an entire division. This is assuming the key bridges, such as one at Narva on the Russian-Estonian border, aren’t destroyed and have to be repaired. Poland only has one wide gauge rail line, which runs from the Krakow region to Ukraine and can’t be used by Russian forces, without capturing Ukraine first. There are no wide gauge lines running from Belarus to Warsaw.

The Russian army does not have enough trucks to meet its logistic requirement more than 90 miles beyond supply dumps. To reach a 180-mile range, the Russian army would have to double truck allocation to 400 trucks for each of the material-technical support brigades.

And we are seeing this in practice:
