On 1 July 2014, as part of the restructuring of Australian operations in the Middle East, Operation Slipper was split into three different operations: ongoing operations in Afghanistan as part of ISAF under Operation Slipper; maritime security operations in the Middle East and counter piracy in the Gulf of Aden under Operation Manitou; and support operations to Slipper and Manitou from a number of locations in the Gulf States, primarily the United Arab Emirates, under Operation Accordion. Approximately 400 personnel are deployed on Operation Slipper, another 550 as part of Accordion, and 250 on Manitou. Australian operations in Afghanistan were scheduled to continue until the ISAF mission concludes in December 2014, while its contribution to the NATO-led "train, advise, assist" mission post-2014 was still to be confirmed. The final Heron UAV detachment left Afghanistan in December 2014.
