Defense planning scenarios and force planning have focused on the traditional or conventional challenger in the past. While state-based conventional threats have not disappeared, it is clear that the United States will dominate conventional adversaries for the foreseeable future. Yet interstate war has not disappeared. It is possible that some state may miscalculate our resolve or commitment or some irresponsible state actor could take actions that might require a U.S. intervention of significant scale. Thus, we need to maintain our traditional combat capabilities for major war. This includes a forcible entry capability by an integrated combined arms team. These skills sets are still the foundation or baseline of our capability for other forms of war.
