This paper presents a review of the advanced materials used in the structure of a novel armor systems and the bodies or frames of the military equipment and vehicles. One of the most often materials engaged in armors are the ceramics among of which the aluminium oxides are the widest spread. Nevertheless, there are more advanced ceramics alike a silicon carbide or boron carbide used for example to shield the pilots of assault helicopters. The section of the paper concerning the materials for the bodies is focused on the high strength steels and the conditions of appropriate joints realization. The examples of the welding imperfections were showed and its influence on the structure integrity was discussed taking into account also others factors.
