READY FOR TODAY – EVOLVING FOR TOMORROW OPERATION HUSKY: ITS RELEVANCE FOR A CONTEMPORARY NATO JOINT TASK FORCE HEADQUARTERS Major James Grant, British Army The aim of Exercise ARRCADE CAESAR 2018 (AC18) was to study the 1943 Allied campaign in Sicily – codenamed Operation HUSKY – and to draw contemporary issues and lessons from a joint task force (JTF) headquarters perspective whilst further developing work on corps recalibration toward a warfighting role. The three key lessons identified were: The importance of a JTF headquarters to ensure unity of purpose and coherence of operational priorities during both the planning and execution of an operation; the need for an agile battle rhythm to enable planning at different speeds (e.g. SOF vs conventional forces); and the difficulties in the governance of occupied territories (e.g. re-occupied NATO territory or occupied non-NATO territory). Exercise AC18 was an ARRC collective training event that included senior representation from a wide variety of NATO formations, to include US Army Europe, affiliated multinational divisions and British Army brigades. The week-long staff ride followed the 1943 Sicilian Campaign from the beach landings on the Avola Coast, across the Catania Plain, through the fortress towns of Centuripe and Adrano and finished looking across the Straits of Messina toward mainland Italy.
