This study examined the adequacy of US Army tactical doctrine for the successful employment of armor in offensive urban operations. Historical case studies on Aachen, Beirut, Grozny, and Baghdad were used to draw lessons learned. These lessons learned were then compared to current US Army tactical doctrine at the company team and platoon levels. The comparisons found US Army tactical doctrine to be adequate to employ armor successfully in offensive urban operations at the company team and platoon levels. However, the comparison of US Army tactical doctrine resulted in a number of recommendations. These recommendations are divided into two groups. First, recommendations are made relative to the lessons learned. Second, recommendations of a general nature t related directly to lessons learned.
