Doctrine provides a military organization with unity of effort and a common philosophy, language, and purpose. This manual, "Theater Army Operations" (FM3-93), discusses the organization and operations of the theater army headquarters, including its role as the Army Service component command (ASCC) to the geographic combatant commander (GCC) and the relationships between the theater army headquarters and the theater enabling commands. The manual also discusses theater army responsibilities for setting the theater, Title 10 functions and responsibilities, generally referred to as the combatant commander's daily operations requirements, as well as the operational employment of the theater army's contingency command post (CCP) to directly mission command limited types of operations.

Field Manual (FM) 6-02, Signal Support to Operations, is the premier Signal doctrine publication, and only field manual. FM 6-02 compiles Signal Corps doctrine into three chapters with supporting appendices that address network operations in support of mission command and unified land operations and the specific tactics and procedures associated with organic and nonorganic Signal forces. The fundamental idea of Signal Corps tactics is the employment and ordered arrangement of Signal forces in a supporting role to provide LandWarNet across the range of military operations. The detailed techniques regarding the ways and methods to accomplish the missions, functions or tasks of the Signal Corps indicated in this FM will be addressed in supporting Army techniques publications (ATPs). Army forces operate worldwide and require a secure and reliable communications capability that rapidly adapts to changing demands.
