Abstract: A smoke forming composition is provided suitable for being explosively dirsed in projectiles, bombs, grenades and the like munitions which is composed of a mixture of finely divided solid particles of smoke forming material and a liquid component in an amount sufficient to densify the solid particles of smoke forming materials to increase the bulk density thereof as well as reducing the danger of ignition or "flashing" of the smoke forming materials when explosively dispersed.

Abstract: A grenade arrangement for forming a visual and infrared screening cloud, having a frangible body, a hollow cylindrical solid compact cohesive mass of compacted generally mutually adhered fine metal flakes of a copper composition, particularly brass, and of submicron thickness and multimicron in lateral dimensions, a cylindrical mass of HE explosive within such hollow cylindrical mass for aerosoling such metal flakes into the atmosphere, and having HE explosive percussisvely activating detonator means, a launch propulsion charge and pyrotechnic delay means between the propulsion charge and the HE explosive detonator.

Abstract: A visual and infrared screening cloud is formed, comprised of an aerosol of fine metal flakes of copper composition, particularly brass, in which the flakes are of submicron thickness and multimicron lateral face dimensions. The cloud is formed by aerosoling a compact generally cohesive mass of copper composition metal flakes of submicron thickness and multimicron lateral dimensions through the action of explosively bursting such compact mass in the atmosphere at the desired cloud location.
