Hello Comet: Howitzers and 155 Long Toms were used on occasion to destroy enemy tanks. At bastogne, Howitzers were used to defend against German tanks when the Germans got too close to town.

I have heard about 155's being used in Italt as AT guns. On one occasion, Audie Murphy called in a 155 barrage on some German tanks attacking a farmhouse that he and his squad were using as a forward observation post.
