The NATO countries howitzers used in Ukraine are varied and modern. Different types and calibers of artillery pieces have been shipped over to Ukraine, so that the Ukrainian Army troops as well as Ukrainian paramilitary units could fight against the advancing Russian Ground Forces.
Aside from main battle tanks and other armored vehicles, the United States, France, Germany, Italy, and Poland sent dozens of towed heavy field howitzers as well as armored, self-propelled guns of all kinds. Nevertheless, many of these guns were either destroyed by Russian missiles or ended up in the hands of the Russian forces due to rampant corruption among the Ukrainian Army officers, who sold all kind of NATO's weapons to the Russians.
