Direct proof of use
Air University Press documents French Mirage F1-CR use in the 2001 War in Afghanistan. It records three Mirage F1-CRs starting a 20-day route-reconnaissance, surveillance, and mapping operation from Dushanbe on October 20, 2004, followed by a deployment of three Mirage 2000Ds and three Mirage F1-CRs on August 6, 2005 for ground-support missions.
AFCENT's December 4, 2007 airpower summary gives an incident-level example after the French fighter detachment moved to Kandahar: a French Mirage 2000 and a Mirage F1-CR conducted shows of force at Musa Qal'eh to deter enemy activity during coalition air operations in Afghanistan.

Deployment timeline
The Mirage F1-CR first appears in the sourced Afghanistan record as a French tactical reconnaissance asset operating from Dushanbe, Tajikistan. Air University Press says the aircraft supported route reconnaissance, surveillance, and mapping in October 2004, then returned in August 2005 alongside Mirage 2000D aircraft for ground-support missions.
The basing posture changed in 2007. Air University Press states that three Mirage 2000Ds moved from Dushanbe to Kandahar on September 26, 2007, followed three weeks later by three Mirage F1-CRs. ECPAD's Afghanistan archive likewise describes the French fighter component of Operation Pamir redeploying from Dushanbe to Kandahar in October 2007 and operating a permanent six-fighter detachment there.

Role in the conflict
The supported Mirage F1 role was French coalition air support rather than Afghan ownership or transfer. ECPAD says the Kandahar fighter detachment operated across Afghanistan for the Afghan army and coalition forces, performed reconnaissance and route-surveillance missions, and alternately fielded Mirage F1 CR, Mirage 2000-D, and Rafale aircraft.
Contemporary French reporting from Kandahar described the Mirage F1 CR mission as tactical reconnaissance first and, when requested by ground forces, fire support. That account also described the aircraft carrying a photographic pod and 250 kg bombs, while noting that fire support followed other deterrent measures such as shows of force.
