Abstract
In order to obtain an explosive smoke grenade, which can be fired from a portable anti-tank weapon, in particular a recoilless infantry weapon, and permits an enemy position or a vehicle to be fogged as quickly as possible, so that the enemy has only a very limited radius of action, a explosive smoke grenade is provided with a time fuse that can be programmed such that the burst charge detonates in the direct vicinity of the enemy position but before the grenade has reached the ground, and releases the smoke-generating active material. In addition, the pyrotechnic active substance arranged between the burst charge and the grenade casing is formed of a plurality of film strips, which are coated with a red-phosphorus-containing incendiary composition (flares). For this purpose, the dimensions of the flares are selected such that they generate a visibility barrier in both the visible and the infrared wavelength regions.
