ARRC JOURNAL Figure 1 – Operation HUSKY, D-Day concept. The campaign was studied from an Allied and Axis perspective, reflecting on the strengths and weaknesses of both sides and drawing lessons for a contemporary JTF headquarters. This essay will provide historical background to three of the key lessons identified. 1. The importance of a JTF headquarters to ensure unity of purpose and coherence of operational priorities. 2. Battle rhythm agility. 3. Governance in occupied territories. It does not include an overall campaign overview as this is covered in Maj. Cox’s excellent piece that complements this. This article also does not cover all of the lessons identified during the exercise, but these are available from the Exercise ARRCADE CAESAR public WiP and the ARRC lessons identified portal (for those posted to the ARRC), or by contacting the author. The importance of a JTF HQ to ensure unity of purpose and coherence of operational priorities Whilst the other two sections in this essay detail the background to standalone lessons identified, this paragraph is an 82 ALLIED RAPID REACTION CORPS amalgam of several individual lessons. Lesson Identified: Understanding and explaining campaign objectives. Clarity in the definition and understanding of campaign objectives and supporting effects is vital. This clarity should also enable the right level of collaboration from the components. Lesson Identified: Components. As well as the standard five components (MCC, LCC, ACC, SOF and JLSG), other areas, such as cyber and CEMA, were discussed in a “component-like” manner. Absolute clarity and shared understanding of the commander’s intent, main effort and end state at the operational level also help to generate collaboration amongst components. Lesson Identified: Influencing the planning process of Multinational Detailed Deployment Plans (MNDPP). The ARRC will need to influence the MNDDP to ensure that the plan delivers the right forces and support at the right time. The strategic direction for Operation HUSKY was the result of the Casablanca conference (14-24 January 1943), which was attended by Prime Minister Churchill and President Roosevelt and their respective military staffs. Following the conference, the Conduct of War in 1943 memorandum, dated 19 January 1943, recommended the occupation of Sicily with the objectives of: • Making the Mediterranean line of communication more secure • Diverting German pressure from the Russian front • Intensifying the pressure on Italy At the time the accepted convention was for British ‘joint’ planning to be conducted by a committee of peers across the three services. Although Gen. Alexander was the deputy commander under the supreme commander, Gen. Eisenhower, the planning had to be agreed to by Alexander in Algiers, Adm. Cunningham in Malta and Air Marshal Tedder in Tunis. However, until May 1943 their focus was on the successful completion of the North African Campaign. Therefore operational planning was left to a relatively junior team of planners led by Maj. Gen. Gairdner, based in Algiers. The geographical dislocation of the component headquarters and lack of a joint headquarters to coordinate planning resulted in significant changes by the various commanders and widespread
