Among the plethora of lessons learned out of Desert Shield/Desert Storm, those linked to command, control, and communications (C3) offer valuable insights into what does and does not work at the Corps level in the preparation for and application of Airland Operations. The scale of joint and combined operations, coupled with the unique expanse of a desert theater of operations, provided a special C3 challenge to Commanders at every level. The author will apply his gulf war experiences to analyze that C3 challenge from the perspective of the VII Corps Tactical Command Post (TAC), operating with a five Division- sized force and a large supporting combat, combat support/combat service support task organization. Starting with the environmental impact on a European-based Corps Headquarters faced with desert theater conditions, the study will focus on planning, preparation, and execution of TAC C3 functions in this Major Regional Conflict (MRC). Organizations, manning, training, and equipping of the TAC will be analyzed relative to the METT-T conditions of the theater campaign. Desert Shield, Desert Storm (both air and ground campaigns), and post-combat TAC functions will be addressed. While cutting across all seven Battlefield Operating Systems (BOS) , the study will remain centered on C3 at the Corps TAC.
