Examines the Armys readiness reporting system in light of changes experienced by Army units in the past decade, particularly the ability of units to adapt to emerging requirements by adding and training up new capabilities quickly.This study examines the readiness reporting system in light of changes experienced by Army units in the past decade, a period in which the Army learned to adapt to emerging requirements by adding new capabilities quickly and flexibly. The current readiness reporting system captures only a portion of those changes in capabilities and has some important limitations. The study recommends ways to improve the reporting system for an adaptive Army.
