Ok, this is wild. Libyan rebels have taken their Mad Max technical pickup trucks to a new level. The video above shows rebels firing what appears to be the turret-mounted 2A28 Grom gun of a Soviet-designed BMP-1 armored personnel carrier from the back of a pickup. Yes, the entire gun turret has been mounted on crude metal supports in the bed of the truck. Note the office swivel chair that has replaced the original gunner's seat. Also watch the guy standing next to the truck reach inside the turret to fire the gun. Classic.
The 2A28 Grom is a 73mm, smoothbore, semi-auto gun that fires the same RPG-style ammunition used in the Soviet-built SPG-9 recoilless gun. While its rounds can pierce armor up to 11 inches thick, it's not very accurate. It's max effective range is about 700 meters. However, its got only a 70-percent chance of hitting a target at a range of 500 meters. That goes down to a 50-percent hit rate at 800 meters when the gun is firing from a still position with no wind. I'm not even sure what the unstabilized gun's accuracy is when it's fired from a moving vehicle.
