As a lieutenant colonel, Field was seconded to the United States Army in 2002 and was an operational planner in the Third Army during the early stages of the United States' Operation Iraqi Freedom and Australia's Operation Falconer during the Iraq War.[1][2][3][4] For his "outstanding achievement in strategic analysis and operational planning" in this role, Field was awarded the Conspicuous Service Cross in November 2003 and the United States Bronze Star Medal in March 2005.[6][4] Field was appointed commanding officer of the 1st Battalion, Royal Australian Regiment (1RAR) from December 2003.[7] In December 2004, Field led a deployment of his battalion's A Company to the Solomon Islands and assumed command of Combined Joint Task Force 635. The Australian government had recently drawn back its military commitment to the Regional Assistance Mission to Solomon Islands (RAMSI). After Australian Federal Police officer Adam Dunning was ambushed and killed while conducting a patrol on 22 December, however, the Australian government committed Field and his soldiers to reinforce RAMSI and enhance security in the region.[8]

In 2015, Field was appointed commander of the 3rd Brigade in Townsville, Queensland. He additionally assumed the role of Queensland State Recovery Coordinator, overseeing the efforts to recover and rebuilt Queensland communities following the severe tropical Cyclone Debbie, in March 2017.[1][2][3] Field handed over command of the 3rd Brigade to Brigadier Scott Winter in November that year and, promoted to major general, was posted to the United States as Vice Director of Operations and Plans in United States Central Command.[11] During the eighteen-month posting, Field oversaw United States and coalition operations in the Middle East. He returned to Australia and succeeded Major General Greg Bilton as Commander Forces Command in June 2019.[3] As Commander Forces Command, Field mobilised approximately 6,000 personnel as part of Operation Bushfire Assist, the Australian Army's response to the severe bushfires that burnt throughout southeast Australia over summer 2019–2020.[12]
