Russian artillery systems
It is hard to work out just how much Russia's artillery has been degraded, but they are tending to fire artillery less than before, according to Nick Reynolds, a research fellow for land warfare at the London-based Royal United Services Institute defense think tank. Part of this could be drawn up to a loss of systems, but also constraints on ammunition supplies, he told Newsweek. The Ukrainian General Staff's figure of 5,000 systems lost could be "pretty close to the mark," said retired British Army Colonel Hamish de Bretton-Gordon, who previously commanded U.K. and NATO chemical, biological, radiological and nuclear defense forces. It is unlikely Russia is able to replenish its artillery systems as quickly as they are being taken out, he told Newsweek.
