This document discusses the need for more than one battlefield framework in US Army doctrine. It provides background on how the military operating environment has changed, necessitating changes to battlefield frameworks. The current deep-close-rear (DCR) framework from FM 100-5 may not be suitable for all environments, such as asymmetric threats. The document analyzes the DCR framework and alternative frameworks to determine the most optimal framework. It concludes that one framework does not fit all environments and future doctrine should account for different battlefield characteristics.
