The scooters would be parachute-dropped in pairs, accompanied by a two-man team. The gun was carried on one scooter, while the ammunition was loaded on the other. Due to the lack of any kind of aiming devices the recoilless rifle was never designed to be fired from the scooter, the gun was mounted on a tripod which was also carried by the scooter, before being fired.
The "Bazooka Vespa" was relatively cheap: Vespas cost roughly US$500 at the time, and the M20s were plentiful. Roughly 800 of these scooters were deployed in the Algerian War.
