The military strategy endorsed by the Pentagon is known as "1421". The first number represents defending the home front. The "four" is the ability to deter hostilities in four global regions. The "two" is the overriding requirement to defeat two enemies nearly simultaneously. The final "one" is having the capability of decisively defeating one of those enemies.
Pentagon planners used a tenet that came to be known as "operational availability," assuming that a transformed force, even while being used in the global war on terror, still should meet US major war requirements.
According to the Pentagon strategy, US troops should be able to repel and occupy an enemy in one war and defeat a second enemy but not necessarily occupy the capital.
The decision is one of the most important that Pentagon leaders make every four years in the congressionally mandated QDR, writes "The Washington Times".
From the two-war requirement, other major decisions flow, such as the number of active and reserve troops, fighter air wings and Navy carrier battle groups, and major weapons systems to be procured.
In this context, it has been proposed that the 10-division active Army would be transformed into 70 mobile brigades. This would allow the armed forces to meet possible future challenges from the "axis of evel" states with fewer soldiers and armaments. Likewise, Pentagon planners believe that the US Navy, with 11 carrier battle groups instead of 12, represents more firepower because of better weapons and intelligence links.
Commenting on the plan, US Defense Secretary Donald Rumsfeld said: "In the XXI century we have to stop thinking about things, numbers of things, and mass, and think also and maybe even first about speed and agility and precision".
