Before they became obsolete, antitank rifles were a way to bring substantial firepower to small infantry teams - but they were never light weight. As with some of the early water cooled heavy machine guns, designers looked for ways to make the weapons more easily transported, and the solution arrived at for the Solothurn S18-1000 20mm cannon was a small wheeled mount. Complete with elevation adjustment to raise the gun just above the available cover and trail arms to secure it against recoil movement, the carriage allowed the gun to be early pulled by its crew or by a draft animal, bicycle, or light motorized vehicle. Most buyers of the guns did not opt to purchase these carriages, however, and they are quite scarce today.
