Russia has a last laugh as West-supplied Howitzers are breaking down in Ukraine - report
“Ukraine is facing technical problems with western artillery amid war with Russia. According to New York Times, one-third of the howitzers sent to Ukraine have developed snags. A U.S. official said that a third of the 350 howitzers sent by the west to Ukraine are out of action. The New York Times reported that the United States Department of Defense is concerned over the development. The U.S. reportedly set up a repair facility in Poland to fix “faulty” weapons, the NYT reported.”
The artillery has to be sent to Poland for routine maintenance, it is part of using the 155, replacing the barrels and other parts to maintain accuracy and effectiveness,
When maintenance is deferred it results in the gun becoming wildly inaccurate and even in blown guns killing the crew, as we see on the Russian side.
