Supporting Units

Although the 100th, like all US infantry divisions in WWII, was a combined arms organization with its own infantry, light and medium artillery, combat engineers, and mechanized cavalry troop, it was supported by a variety of separate Corps and Army assets in the execution of several missions.

Some of these outfits remained attached to the 100th, in part or entirely, throughout almost all of its combat in the ETO. By contributing unique battlefield capabilities and providing mobility or firepower beyond that available from integral Division resources, each of them played a vital role in the Division’s victories.
