Open-source documentation places the Bandvagn 206 in Canadian service during Operation Anaconda, the March 2002 coalition operation in Afghanistan's Shah-i-Khot area. Canadian Defence Review's BV 206 equipment profile says the Canadian Army first used the carrier in combat during Operation Anaconda in March 2002.
GlobalSecurity's Small Unit Support Vehicle profile gives a more specific account, identifying Canadian BV-206 AMVs attached to the 3rd Battalion, Princess Patricia's Canadian Light Infantry Battle Group and saying they were used in Operation Anaconda after U.S. Army CH-47D Chinooks airlifted them into combat zones.

Timeline
Operation Anaconda began on 2 March 2002 as a coalition operation against al-Qaeda and Taliban forces in mountainous eastern Afghanistan. Army University Press describes the Shah-i-Khot Valley battle area as rugged, cold, and high-altitude terrain, with coalition forces including U.S. troops and special operations personnel from several partner nations.
During the same operation, Canadian BV 206 carriers were used as mobility support for Canadian troops. Defense Industry Daily's Afghanistan appendix says Canadian Bv206s served with the Princess Patricia Canadian Light Infantry Battle Group, attached to the U.S. Army's 2nd Brigade, 10th Mountain Division, and were carried inside CH-47D Chinooks to an objective called The Whaleback during Operation Harpoon.

Narrative
The documented Afghanistan role for the Bandvagn 206 was all-terrain combat lift, not a weapons-carrier role. The cited accounts describe Canadian use of the vehicle to move infantry and loads over rough mountain terrain at altitude, where foot movement with full combat gear imposed a heavy physical burden.
That role matched the vehicle's design. The Canadian Army describes the BV 206 as an all-terrain transport vehicle with four driven tracks, amphibious capability, and a large track area for deep snow and soft ground. GlobalSecurity similarly describes the SUSV/BV-206 as an articulated, tracked, multi-role transport vehicle able to move 17 combat-equipped soldiers and to be transported by aircraft and helicopters including the CH-47D.
The available sources support Canadian deployment and operational use during Operation Anaconda, including air movement by CH-47D and tactical mobility around Operation Harpoon. They do not identify individual vehicle serials, a complete number of BV 206s used, or a specific firing engagement by the vehicle itself.
