The howitzers, which have to be towed into position and then can be moved again after firing, are able to maintain a steady stream of fire that can be used to force Russian forces to duck into trenches while Ukrainian infantry troops advance.
“We think it could have significant additional firepower for the Ukrainians,” one of the senior defense officials said. “If we didn’t believe that, we wouldn’t have moved forward with that many howitzers and that many more rounds.”
The decision was made, the official said, in consultation with the Ukrainian military.
“We think it will be a significant contributor, and a meaningful contributor to their ability to continue to defend themselves in the Donbas,” the official added.
Some of the first batch of 18 howitzers have already arrived in Ukraine, having been drawn from U.S. Army and Marine Corps inventories in the United States, the Pentagon said.
Additional howitzers will arrive over the weekend, when more than 50 Ukrainian artillery soldiers are expected to complete their training on the new American guns at an undisclosed location outside their country, and then return to the fight against the Russians.
