This photo shows how a handful of sandbags can be a method of frontal protection. Held in place by a length of rope, the sand bags would provide acceptable protection from small arms fire. Interestingly, the hood bows and canvas top are still in place. Gunner appears to be armed with the Australian L2A1 automatic rifle.
This unique setup would be quite a sight to behold at a military car show or event. Any REMLR members want to give it a go?
