Abstract: A hand grenade comprising a plurality of explosive elements containing charges, the detonation of which timewise, is not ascertainable. The explosive elements are connected via a control-processing- and storage-electronics, in which from one or a plurality of signal transmitters, predetermined criterion such as definite amplitudes and/or frequencies and/or gradients which statistically occur, are led off and/or transformed and correspondingly processed for triggering or release of an ignition impulse for each individual explosive charge, respectively.
