The war on terrorism will pose some challenges that the Army's transformation does not fully address. Earlier portions of this briefing suggest that the war will include new classes of targets for which the Army may face some shortfalls or gaps in capabilities. Viewed in terms of responsiveness and combat power, wartime operations are likely to require greater combat power for a given response speed than the Army has traditionally been able to provide.
This figure depicts the trade-offs between time to deploy combat forces and combat power delivered—both the relationship that exists today and that needed for counterterror strike operations. The larger horizontal triangle captures the spectrum of traditional operations that the U.S. Army routinely engages in and is well designed for. At the lower end would be current ARSOF direct action and light force strikes and raids. These forces are responsive and have unique capabilities but have limited firepower, force protection, and mobility. At the upper end of the triangle are missions conducted by heavy maneuver combat brigades and divisions. Tremendous combat power resides in these forces, but it comes at the expense of responsiveness. In the middle of the triangle are missions
