Southern Jackaroo
Words Captain Thomas H. de Vries, Marine Rotational Force – Darwin Photos Barrie Collins In the heart of the Australian Outback, US Marines, Australian soldiers, and Japan Ground SelfDefense Force soldiers assembled and successfully conducted Exercise Southern Jackaroo 2021 in June. The trilateral exercise, held over a two-week period, was a tangible demonstration of multinational interoperability, where the forces worked through logistical and cultural challenges that tested the ability of each of the militaries to mutually support one another. The exercise began with an opening ceremony at Robertson Barracks, home of the Australian Army’s 1st Brigade, where commanders addressed a formation of Australian, Japanese and US troops. They spoke on themes of enhanced cooperation between each force and the importance of building deep, personal and professional relationships with one another. To overcome communication barriers, the force integrated teams of military interpreters throughout 78
the formations in order to best facilitate understanding amongst each other. Japanese liaison officer at 1st Brigade HQ Australian Army Captain David Ferwerda said they built a multirank team of interpreters, drawn from the ADF and JSDF, to bridge the gap from the lowest ranks up to the command group. Training commenced with urban breaching operations at the Urban Operations Training Facility at Mount Bundey, where all three forces demonstrated their tactics, techniques and procedures for manoeuvring through urban terrain. Leaders frequently reviewed the patrols and breaches to learn from one another and, if required, integrate squads in future operations. Simultaneously, US cannoneers from Mike Battery, 1st Battalion, 7th Marine Regiment (Reinforced) and the Australian 103rd Battery, 8th/12th Regiment, Royal Australian Artillery, established a combined gun line of six M777 howitzers, where they participated in fire missions directed by US and Australian fire-support coordination centres. MRF-D Command Element fires officer Captain Eric vanHorn said the time and effort that the Marines and their Australian friends invested during the exercise – and would continue to invest to advance interoperability – demonstrated the strength of the ANZUS alliance. “Coordinating fires came easy to us because of a shared purpose, built upon a long history of partnership for more than a century,” Captain vanHorn said. To conclude the first week of training, troops from all three militaries met at a combined marksmanship range, where snipers demonstrated advanced shooting techniques to engage targets at maximum effective range. Japan Ground Self-Defense Force Colonel Kosyo Mizoguchi, commanding officer 50th Infantry Regiment, said the opportunities presented by training with Australian and US forces was very important. “It is also very meaningful because Australia has very broad training areas, so we can conduct long-range shooting,” Colonel Mizoguchi said.
