In a multi-burst diversionary device (10) containing a number of pyrotechnic cartridges (22) arranged in a series and a firing arrangement (14), a first of the cartridges is ignited by the firing arrangement, the remaining cartridges are each ignited sequentially by the flash of pressure and heat (hot gasses) produced when a previous cartridge in the series deflagrates. The device has a housing (12) defining a number of compartments (20) in which the cartridges are received. The housing defines flow paths interconnecting the compartments in series and the first compartment with the firing arrangement. Each compartment is also fluidly connected with atmosphere.

The invention a multi-purpose, multi-reusable, multi-ejectable grenade and anti rioting device in a single unit. Explosion(s) occur by being thrown after setting the desire pyrotechnic effects. Further Characteristics in that principally consist of four quarter mountable oval shape charges that ejected or launch after being toss and impact with target surface or target object that will occur during detonation process hence create the desired pyrotechnic effects.

A multi-purpose munition operates in either a blast mode or a fragmentation mode according to a user input. When operating in the fragmentation mode, a fuze initiates a main explosive fill of the munition which in turn disperses fragments formed from a fragmentation layer of the munition. When operating in a blast mode, prior to initiating the main explosive fill, the fuze initiates a secondary energetic layer which discards the fragmentation layer. The fuze then initiates the main explosive fill thereby producing a blast effect.

A multi-purpose non-lethal blunt trauma grenade which produces both blunt trauma effects as well as light and sound effects. The non-lethal blunt trauma grenade comprises a main charge holder configured for not fragmenting upon ignition of the main charge and which includes a plurality of vent holes sized and oriented to balance the propulsive force of gases generated by a main charge.
