On 14 June 1993, the Army issued its new keystone doctrine in Field Manual (FM) 100-5. It clearly and concisely expresses how the Army intends to conduct war and operations other than war (OOTW) now and into the twenty-first century. This manual, "Division Operations (FM 71-100)," builds on the doctrine principles describe in FM 100-5 as well as those described in FM 100-15. It applies these doctrinal principles and new concepts to the full dimension of Army division operations. Additionally, this manual is consistent with joint doctrine. Joint doctrine is Army doctrine. This is the capstone manual for Army division operations. This manual will assist division commanders, their staffs, and subordinate commanders in planning and conducting division operations. It will guide many organizations regarding the capabilities, limitations, and employment of US Army divisions. It also will guide the development of subordinate unit doctrine. FM 71-100 sets forth doctrinal principles that apply to all types of Army divisions.
