Historically, stability operations are not a new mission for the U.S. military. Based on the identified historical familiarity of the Army with stability operations, one would assume that the Army, being an adaptive and learning organization, would be better prepared or capable of conducting stability operations. However, these missions present significant challenges to the Army. This strategy research project examined two Operations (OPERATION JUST CAUSE, Panama1989 and OPERATION IRAQI FREEDOM 2003) and identified three challenges to the Army in conducting stability operations. Specifically, they are challenges in: 1) doctrine; 2) culture; and 3) interagency coordination. This research project concludes that the Army must maintain the current doctrinal focus of stability operations as a core mission; the Army culture must inculcate stability operations; and the Army must continue the refinement of interagency coordination.
