This WSJ report traces the development of rail, trucking, container shipping and forklift use in Germany, Russia and the US. The World Bank Logistics Index shows Germany ranking first, the US 14th, China 26th, Russia 75th out of 160 countries. 

Russia's military relies on a supply system that uses crates instead of container shipping, not much use of forklifts, and relies on rail and conscript labor. During the invasion of Ukraine in April Russian supply lines that did not control rail failed to supply forces leading to slow progress. Because of dense rail lines in the eastern Donbas region Russian supply lines have worked to sustain advances. About 750 miles of rail lines have also been repaired by a special force set up for this purpose. 

In a larger sense the problem of logistics and supplying front lines remains. This report shows the contrast between the development of Russian logistics and American logistics described by military experts in the US. The Russian system evolved in the early years of the 20th century based on conscript or free and abundant labor compared to the US where labor was scarce and costly. Automation progressed rapidly with American business taking up use of forklifts and containers during the 1940's extending to its use in the military. During the Vietnam war Cam Ranh Bay US bases were converted to modern container and forklift use. Russia continued through the sixties till today with a different and less automated system of logistics and movement of goods. 
 

The use of modern logistics in Russia is limited to the amount of freight that gets moved in Colombia and much less than France says this report in WSJ. Much of the industrial base in Russia is built around oil and gas exports and manufacturing with movement of supply chain parts has never taken the importance that it has in Germany or the US.

This limits the capacity of the Russian military outside the rail lines located towns and cities in Donbas where it has recently made gains.
