Abstract: Panels and their modules, such as for walls and roofs, are disclosed that provide armored shelter for protecting people and equipment from ballistic projectiles and mortar attacks. Each module is made from multiple co-parallel plates arranged in a stack, spaced apart, and held together along their sides by side elements.
