The MRF-D has departed after undertaking a range of exercises, which strengthened cooperation and interoperability with the Australian Defence Force.

The 1100 US Marines arrived in a series of tranches and completed a mandatory 14-day quarantine, prior to starting their training; and, were tested for COVID-19 on entry to Australia and a second time prior to exiting quarantine.

One of the Marines tested positive for coronavirus while in quarantine.

The rotation achieved significant joint training objectives and outcomes.

The first key activity, Exercise Loobye, saw US Air Force B-1 and B-2 bombers integrate with the Australian Army and the MRF-D in a highly advanced training activity, allowing both ADF and US forces the opportunity to practice their skills.

While they did not land in the NT, it is planned in years to come they will be able to use the Tindal RAAF Base once the upgrades there are complete.

The second key activity, Exercise Koolendong, focused on a complex scenario, which progressed to high-end live-fire training, designed to build interoperability in support of the ADF and US Marines' ability to respond to a range of crises in the region.

The modified MRF-D operated between June and October 2020 reached an approximate size of 1100 personnel.

Planning is underway for the next year's MRF-D, which will mark its 10-year anniversary.
