Why logistics are too important to be left to the generals

Submission Statement

This article is the third in a series by the Economist focused on lessons learned from the Ukraine war. The articles are written for a layman audience, but even dedicated watchers can derive value from the interviews and novel information sprinkled throughout. I plan on posting them in sequence here, and the full set of 7 articles can be found here.

"Logisticians are a sad and embittered race of men who are very much in demand in war, and who sink resentfully into obscurity in peace. They deal only in facts, but must work for men who merchant in theories. They emerge during war because war is very much a fact. They disappear in peace because peace is mostly theory."

Whatever theories the Russian army was operating under when they rolled into Ukraine on February 24th were quickly dispelled by the cold hard facts of logistical insufficiency. The feasibility, or lack thereof, of supplying forward positions has underpinned some of Russia's most stunning retreats throughout the war. This article explains the aspects of Russian doctrine that led to their logistical difficulties, as well as Ukraine's efforts to avoid the same while juggling the most diverse arsenal of weapons anywhere in the world.

Western armies tend to have high “tooth-to-tail” ratios, with as many as ten support personnel for every combat soldier. Russia has fewer. Like the Soviet Union, it relies on moving fuel by pipeline and other material by rail. That can be highly efficient: Russia’s army managed to shift and fire a cumulative total of 700,000 tonnes of shells and rockets in the first five months of the war. But it ties the army to railheads and large depots nearby. That has turned out to be a problem. In the spring of 2022 Russian shellfire was grinding down Ukraine’s army in the eastern Donbas. Russian guns out-pounded Ukrainian batteries by three to one. That changed when Ukraine acquired American himars launchers and European systems capable of firing rockets precisely over 70km. Suddenly it could hit Russian fuel depots and ammo dumps well behind the front lines. Many had not budged since 2014.

The ensuing bonfire of supplies starved Russian guns of ammo. It forced Russia to switch from big, centralised depots to smaller, dispersed ones farther from the front. The longer distances to haul heavy shells, plus a paucity of trucks, pallets and logisticians, threw grit into the wheels of Russia’s military machine. Ukrainian officials say this paved the way for successful offensives in Kherson and Kharkiv. Nico Lange, a former German defence official, says that a Ukrainian soldier chalked up this success to understanding Russia’s logistical weaknesses: “It’s basically like fighting ourselves from ten to 15 years ago.”

The problem is keeping the weapons going once they arrive. Steven Anderson, a retired American general who oversaw logistics in Iraq, says that the “operational readiness rate” for equipment there was 95%. Anything below 90% would get a commander pulled up in front of bosses. In Ukraine anecdotal data suggests it is only around 50%, he says. “Half of what we give them is broken at any given time and they’re struggling mightily.” For much of the war, Ukraine’s exhausted artillery pieces have been sent to eastern Europe to fix. Since the autumn, more can be repaired in Kryvyi Rih, an industrial city near the southern front. But its capacity is limited. Mr Anderson complains that less than 4% of American aid has been allocated to support and maintenance.

That is forcing Ukraine to pioneer new forms of wartime sustainment. Ukrainian volunteers are 3d-printing spare parts in buildings a few hours’ drive from the front. Key to this is decentralisation. Individual brigades often find their own parts rather than asking the general staff’s logistics command. “They just go to the garage,” says one source familiar with the underground supply chain, “and say: I need this piece. Can you do it?” Separately, America’s Airborne XVIII Corps is using algorithms to estimate the barrel life of Ukrainian howitzers, when they need spare parts and when fresh munitions must be pushed to the front.

America has grown used to sustaining wars thousands of miles away with scant threats to ships, planes and trucks carrying supplies to ports, airfields and depots. Those days are over. “Decades of wargaming, analysis, and empirical evidence suggest that attacking [American] logistical dependencies…is the most effective way of fighting the United States,” concludes Chris Dougherty, a former Pentagon planner, in a paper. Chinese attacks on logistics have “paralysed” American forces in war games, he says. He urges the Pentagon to shift money from combat forces to logistics. Armies need to position more stocks forward and “live off the land” to acquire fuel, lubricants, food and spare parts locally. Troops must fight on their own for weeks with minimal support, he adds. Logistics have long had “second-class status”, he says, despite a “starring role” in military history. Ukraine shows that anew
