The purpose of this thesis is to examine how the Army acquires enablers to conduct Joint Training at the Brigade level during a Combat Training Center rotation at the National Training Center. This study is a qualitative research project, which analyzes the procedures that must be followed by an Army Brigade Combat Team (BCT) to insure requested joint enablers are allocated for the BCT's training at the National Training Center. This research project examines joint doctrine and Chairman of the Joint Chiefs of Staff (CJCS) manuals to determine the origins of Joint Mission Essential Task List (JMETL) developed at the combatant commander level. It further uses service doctrine and manuals to link joint doctrine and the combatant commander JMETL to the brigade combat team as it submits its mission letter for a mission rehearsal exercise (MRE) at the National Training Center (NTC). This thesis will then examine the duties and responsibilities of Joint Forces Command (JFCOM), Forces Command (FORSCOM), and Training and Doctrine Command (TRADOC) in supporting the BCT joint enabler request for a MRE. Finally, recommended options based on the analysis will be presented in order to improve allocation of Joint enabler participation for the BCT's training at the National Training Center. Additionally, Army and Joint publications could be updated to correct identified deficiencies and address the Joint Training procedures in applicable TRADOC and FORSCOM publications.
