A training hand-grenade comprises a housing optionally interconnected with a safety lever for activating the train grenade. The aforesaid train grenade accommodates at least one blast simulator selected from a group consisting of a speaker for generating an acoustical blast imitation, one or more light emitters, a smoke generator and any combination thereof. The train grenade comprises a processor, intercommoned with a power supply and the blast simulator, configured to operate the blast simulator in one of two or more preset modes of operation. Each of the modes of operation is characterized a predefined combination of blast acoustic parameters, and optionally also light and smoke effects.
