Direct proof of use
The Black Hornet is directly documented in the 2001 War in Afghanistan through British and U.S. patrol use. On February 4, 2013, the UK Ministry of Defence said British troops in Afghanistan were using Black Hornet Nano unmanned air vehicles as handheld surveillance helicopters, with imagery shown on a handheld terminal and with patrol use around corners, over walls, and across exposed ground.
U.S. use is documented later in the war. Stars and Stripes reported on August 12, 2019, that paratroopers from the U.S. Army 3rd Brigade Combat Team, 82nd Airborne Division, used the Black Hornet Personal Reconnaissance System during a Kandahar province foot patrol, where the system provided overhead surveillance during a counterterrorism mission.

Narrative
In British service, the Black Hornet was used as a soldier-carried reconnaissance aid rather than as an armed UAV. The UK Ministry of Defence described the air vehicle as a small camera-equipped system that supplied full-motion video and still images to troops on the ground, and identified Prox Dynamics of Norway as the developer under a UK procurement route for 160 units.
The British Afghanistan role centered on immediate patrol awareness. The Ministry of Defence described soldiers using the system to inspect hidden dangers around obstacles, and quoted a Brigade Reconnaissance Force soldier in Afghanistan saying it was used to look for insurgent firing points and to check exposed ground before crossing.
The U.S. Army appearance came through the Soldier Borne Sensor fielding path. Stars and Stripes reported in June 2019 that 82nd Airborne troops had received Black Hornet Personal Reconnaissance Systems and training before deploying to Kandahar. In August 2019, the same outlet reported actual use by paratroopers in Kandahar province, with Army photos showing a Black Hornet launched in support of a foot patrol and the unit routinely employing the system to reduce combat risk.
