seems to me the HUMMER was built for this job but then everybody complained because it didn't have armor... well neither did the Jeep it replaced seems to me the HUMMER was built for this job but then everybody complained because it didn't have armor... well neither did the Jeep it replacedread post 30 and 34. interested in your thoughts.
Instead of steel armor I would suggest the use of synthetic materials such as fiberglass/Kevlar/aluminum/carbide laminates for light weight but good shrapnel/fragments protection mounted on the new 4 door jeep frames.
Low tech for the most part , proven design (jeeps been around for better than 70 years) light weight . Also look into using small pick-up trucks with fiberglass/Kevlar/aluminum/carbide laminate sheets that are cut to fit like pieces of plywood .
This will allow the most flexibility/lowest cost/lightest weight/highest protection .
You will not get light weight “bullet proof” vehicles even with modern synthetic materials(against rifles/machine guns) however you can go a hell of along way towards protecting folks from bomb blasts & shrapnel fragments without the weight of steel armor.
