Gun truck

A gun truck is an armored vehicle with one or more crew-served weapons used by units of regular armies or other official government armed forces to escort military convoys in regions subject to ambush by guerrilla forces, defend airfields, provide perimeter defense, or serve as mobile pillboxes for Home Guard-type defensive units. Gun trucks typically have Improvised vehicle armor, such as scrap metal, concrete, gravel, or sandbags, which is added to a heavy truck.
