Marine Rotational Force-Darwin is a United States Marine Corps Marine Air-Ground Task Force based at Matilda Lines at Robertson Barracks and at RAAF Base Darwin. On 16 November 2011, Prime Minister Julia Gillard and President Barack Obama announced that starting in 2012 US Marines would deploy to Darwin on a rotational basis for about six months to conduct exercises and train with the Australian Defence Force in the Northern Territory. The first rotation of about 200 US Marines deployed to Australia in April 2012. On 14 June 2013, the Prime Minister announced that in 2014 the size of the deployment would increase to 1150 US Marines to be based at Robertson Barracks. Since then, that number has increased to 2,500. During the six-month deployment, Marines train with their Australian counterparts in live fire exercises which builds comradery and combat effectiveness between the two coalition forces. Both forces train the other in their military methods which include artillery fire, Infantry tactics, communications equipment, and other various military trainings. From Wikipedia
