"Logistics make up as much as nine tenths of the business of war." -- Martin van Creveld.
Looking for tables of ammunition expenditure for various types of military operations, I found an interesting article from 1999: "Soft Log" and Concrete Canyons: Russian Urban Combat Logistics in Grozny. It may be of interest to those who are thinking through future problems of civil war here, especially in urban areas.
Although logistics is a major concern of warfare, comparatively little has been written about logistics when compared to writings about the tactical and strategic aspects of various wars. As a subset, very little has been written about logistical support of urban combat. One historic precept of urban combat logistics is that ammunition expenditure increases dramatically when fighting in cities. Recent Russian experience in fighting for the Chechen capital city of Grozny in January/February 1995 demonstrated that ammunition resupply was not the only problem. Demands on maintenance, supply, transport and medical support surpassed the capabilities of TO&E logistics units. Logistics demands were further increased by the requirement to provide humanitarian relief during the course of the fighting. . .
Besides small arms ammunition, front-line infantry used copious amounts of hand grenades, smoke grenades, smoke pots, demolition charges, flame thrower rounds, RPG-7 rounds and single-shot disposable antitank grenade launchers. Tear gas grenades were often required at certain points on the battlefield and had to be pushed forward. The front line infantry also had an immediate need for quantities of grappling hooks and ropes, light-weight ladders and night vision equipment. Many of these items were delivered by emergency airlift to Mozdok. Where there was a shortage of night-vision equipment, the Russians used mounted and dismounted searchlights to illuminate the battlefield and dazzle the Chechen opposition.Mortars produced the most casualties on both sides and HE and smoke mortar ammunition was always in demand. Artillery was also used, often in a direct fire role. One-fifth of the artillery ammunition fired was smoke or white phosphorous-consequently these were high-demand items. Smoke screened infantry movement and white phosphorus smoke had the additional advantage (or disadvantage) of being lethal, capable of penetrating existing protective mask filters and not being banned by any international conventions.One of the most effective Russian weapons in city fighting was the venerable ZSU 23-4--a lightly-armored self-propelled antiaircraft gun whose four 23mm barrels spat out up to 3,200 rounds per minute. The elevation and deflection of the system, as with its modern equivalent, the 2S6, provided an excellent counter-gunner weapon for city fighting. However, keeping the ZSU 23-4 and the 2S6 in 23mm and 30mm ammunition was a constant problem.Clean drinking water was a high-demand item, but delivery of clean water forward often proved too difficult. Individual water treatment panticides took too long to work. Fighting is thirsty work and soldiers drank what was available. Viral hepatitis and cholera were the result.POL was critical as the Russians used over 200,000 tons of POL during the battle for Grozny. Captured POL stocks proved very useful to the Russian ground forces. A major problem was moving the POL stocks up close to the units in contact.
