 To do this, the Pentomic concept organized what would normally be parts of several different units into a more balanced division, reducing the need for communications between different command structures that would introduce delays.After Taylor designed the Pentomic concept, he promoted Westmoreland to what was then the youngest Major General in the US Army to command Taylor's former wartime command, the recently reactivated 101st Airborne Division.This would be the first unit to be reconfigured in the Pentomic structure.
