Dutch-led Provincial Reconstruction Team, operating as part of Task Force Uruzgan and based at Forward Operating Base Ripley, outside of Tarin Kowt. However, as the Australian commitment expanded, by 2010 the task force had evolved into a combined arms battalion-sized battle group consisting of infantry, engineers, cavalry, artillery and logistic elements, usually based on a unit of the Royal Australian Regiment. Known as the Mentoring Task Force (MTF), it formed part of a multinational brigade known as Combined Team Uruzgan and was tasked with counter-insurgency operations in conjunction with United States and other coalition forces. Partnered with the 4th Brigade, 205th Corps of the Afghan National Army (ANA), it operated throughout Uruzgan Province. While attached to MTF-1, soldiers from Combat Team Delta (based on D Company, 6 RAR) took part in heavy fighting during the Battle of Derapet in Deh Rahwod on 24 August 2010. Corporal Daniel Keighran was later awarded the Victoria Cross for Australia for his role in the battle, the first member of the Royal Australian Regiment to receive the award. The task force was withdrawn in late 2013 following the handover of the province to Afghan forces, although a small force protection element remains as part of the ongoing but reduced Australian training and advisory mission. Twelve members of the regiment have been killed in Afghanistan. Special Operations The Special Air Service Regiment owes its heritage to the RAR. Originally formed as the 1st SAS Company in 1957, in 1960 it became an independent company of the RAR and was tasked with providing the army's special operations capability. The SASR became a regiment in its own right on 20 August 1964, severing the link with the RAR at this time. Re-raised as a commando battalion from 1997, 4 RAR (Commando) served in East Timor as a conventional light-role battalion in 2001, before focusing on the development of its special operations capability. In this role the battalion was designed to be a flexible, self-contained force element able to deploy at short notice to undertake offensive operations in support of Australia's national interests. Once full operational capability was reached, elements of 4 RAR (Commando) would serve in Timor Leste, Iraq and Afghanistan, as well as providing a domestic counter terrorism capability as part of Tactical assault group (East). In 2009, 4 RAR (Commando) was renamed the 2nd Commando Regiment, and as such is no longer part of the
