armor plating is provided for armored land vehicles or watercraft , the armor having a base armor plate and an additional armor plate fixed thereto on the enemy side , such that it can be removed . a structural component can be used as a base armor plate for such vehicles , and comprises a layered structure with a core composite having an inner honeycomb core and at least one covering layer . the layered structure does not contain supporting metal layers or ceramic , hard material layers . another essential characteristic is the use of fixture elements which are anchored in the core composite to allow additional armor plating to be detachably fixed on the enemy side . the core composite therefore essentially offers basic protection itself , while also acting as the carrier structure for interchangeable additional armor plating .
