2009, the US president announced a major troop increase that sent another 30,000 troops to Afghanistan. The Canadian troops remained mostly active in the Panjwai and Kandahar districts, where they were located at the end of 2009. Canadians were also active in the Zhari and Daman districts. In February 2010, Canadian air forces and ground troops from 3PPCLI took part in the highly publicized Marja offensive. In early 2010, Task Force Kandahar also contributed to creating the 3rd brigade of the 205th Afghan National Army (ANA) Corps that was deployed in Kandahar and Helmand province. In April 2010 the 1st Battalion Royal Canadian Regiment (1RCR), along with O Company of the 3rd Battalion Royal Canadian Regiment (3RCR), was deployed to relieve PPCLI in the southern districts of Kandahar province. In late May 2010, heavy fighting ensued and continued for much of the summer. During this time, two major operations involving about 160 troops along with two platoons of ANA were conducted under the name Operation Azida 1 and Operation Azida 2. 7 Platoon 3RCR's involvement in the operations over three months confronted them with as many as 75 skirmishes with Taliban forces, and approximately 50–75 improvised explosive devices (IEDs) were found. On one occasion, a Chinook helicopter was struck in flight by an insurgent RPG. This resulted in a hard landing, and destruction of the helicopter, but with no reported serious injuries. The violent clashes and skirmishes continued through the end of August, leaving O Company 3RCR and their combat attachments with over a dozen serious injuries. Two weeks later Canadian Forces transferred Kandahar city to US forces, at which point most of Canada's forces were in the Panjwai district, Dand and Daman. On 27 November 2010, in the tenth and final troop rotation, the 1st Battalion of the Royal 22e Régiment took over, marking the final rotation before Canada's withdrawal from Afghanistan. Canada withdrew the bulk of its troops from Afghanistan in 2011, with the Infantry Battle Group withdrawn by the end of July (handover of battlespace was completed 6 July, and all Canadian Forces personnel and equipment were withdrawn from Kandahar by the end of December. In September 2008, Conservative leader Stephen Harper had pledged the withdrawal by saying that a decade at war is enough, having extended the withdrawal deadline twice previously. He acknowledged that neither the Canadian public nor the troops themselves had any appetite to
