The Italian equivilents of the LRDG/SAS were the Compagnie Arditi Camionettisti who were equipped with the Camionetta 'Sahariana' AS 42. I have made a start on one of these units with the Italeri kit. It was a lot of parts, but builds into a lovely model. The 20mm Breda is particularly fine, but fragile so it's best in the vehicle.
I still need to find some crew for these. A typical unit would consisted of 10 vehicles, which is represented by two in Rapid Fire terms. More details can be found on the Commando Supremo site
Finally for comparison I have added the BP casts 20mm Breda AA, which can clearly be seen as overscale in comparison with the Bredas on the vehicles.
