Nearly 70 years after it was first produced by Mauser during WWII, the MG 151/20 20mm autocannon is still being manufactured by French firm Nexter. In the below photos it is hooked up to one of those fancy remote control turrets which is mounted to a stripped-down raider version of the Panhards VBL (Véhicule Blindé Léger).
[ Many thanks to Aurelien for proving the photo and information. ]
UPDATE: My mistake. It’s not a remote controlled turret. I mistook the holo/red dot sight for a camera.
