Slipper. This combat role continued until the end of 2013 when it was replaced by a training contingent operating under Operation Highroad until 2021. After the Gulf War the UN imposed heavy restrictions on Iraq to stop them producing any Weapon of mass destruction. In the early 21st century, the US accused Iraq of possessing these weapons and promoted unsubstantiated allegations, and requested that the UN invade the country in response, a motion which Australia supported. The UN denied this motion, however, it did not stop a coalition, that Australia joined, invading the country; thus starting the Iraq War on 19 March 2003. Between April 2015 and June 2020, the Army deployed a 300-strong element to Iraq, designated as Task Group Taji, as part of Operation Okra. In support of a capacity building mission, Task Group Taji's main role was to provide training to Iraqi forces, during which Australian troops have served alongside counterparts from New Zealand.
