This patch was created to commemorate the exercise with Australian Force. It says “MRF-D ACE” across the top and “HIGHLY KOALAFIED” along the bottom with the Aussie Flag and “Koala” in the middle. Service members at Marine Corps Air Station Kaneohe Bay departed here, March 25, to begin a six-month deployment to AustraliaÕs Northern Territory as part of Marine Rotational Force Ð Darwin. Approximately 100 Marines from Marine Heavy Helicopter Squadron 463 (HMH-463) and Marine Aviation Logistics Squadron 24 (MALS-24), as well as four CH-53E Super Stallion helicopters partook in MRF-D as part of an Aviation Combat Element. This marks the first year in which such an ACE has been part of MRF-D.
