[12] In August 2003, he was appointed deputy commander of the International Security Assistance Force in Afghanistan, which would later become a NATO mission, working under a United Nations Chapter 7 mandate.

[8] Leslie led the mission efforts which focused on stability, counter insurgency, and counter-terrorism operations, during which many hundreds of tanks, rocket launchers and heavy artillery were taken away from various warlords.

[17] In this position, Leslie was responsible for releasing the 2011 Report on Transformation, which, among other changes, recommended significantly cutting headquarters' budgets and transferring the funds to front line combat units.

[20] Before officially retiring from military service, Leslie was approached by several members of the Prime Minister's Office to inquire about whether he was interested in heading a federal department or organization.

These included discussions with Prime Minister Harper's Deputy Chiefs of Staff Derek Vanstone and Jenni Byrne about heading the Canadian Museum of Civilization.
