A shot resistant armour coating is produced by positioning geometric bodies (2,5,6) in a line so that they contact each other and fixing their position by sticking them together. The bodies have curved outer surfaces and are balls ellipsoid, pareboloid or polyhedron in shape. The bodies are stuck together via a metal-oxide nitride and/or carbide layer (4,7,8). The layers of bodies may then be sandwiched between outer layers (3,9). Each ball of one layer is positioned in the hole between two balls of an adjacent layer. The inner layer (9) is pref. a plastic foam with a glass fibre reinforced layer (11). The bodies are pref. made of ceramic such as Al2O3 with adhesion layers being sprayed on to a thickness of 0.1-2 mm, pref. 0.3-1 mm. USE/ADVANTAGE - Armour protecting vehicles and aircraft. The coating has a low weight and any shot hit it is at least partially deflected due to the surface shape of the bodies.
