A stun grenade includes a fuze assembly secured to a housing adjacent gas outlet ports. The fuze assembly includes a fuze body having contact surfaces located in the flow path of the gas from the outlet ports so that gas flowing from the outlet ports impinges on the contact surfaces. The contact surfaces of the fuze body extend at an angle of no more than about 50 degrees to the first direction.

A non-pyrotechnic disseminator includes a body portion with a cover; a first compartment that holds disseminating materials; a spring-loaded piston; a cable connecting the piston to a base of the body portion: a second compartment adjacent to the first compartment; a control mechanism; and an initiator mechanism. The control mechanism sets a delay timing countdown for initiation of dissemination of the disseminating materials out of the body portion. The initiator mechanism begins the delay timing countdown. The second compartment includes a delay fuze module; and a cutting mechanism in contact with the cable. The delay fuze module processes the delay timing countdown, and upon expiration of the countdown, sends a signal to the cutting mechanism to cut the cable. When the cable cuts, the spring uncoils and pushes the piston, which forces the disseminating materials out of the body portion by rupturing the cover.

A diversionary device including a triggering mechanism, a payload and a compressed gas container containing a compressed gas. The compressed gas is non-flammable. The triggering mechanism is coupled to the compressed gas container, and conveys at least some of the gas from the compressed gas container to the payload after a predetermined delay after the triggering mechanism is activated. The gas conveyed to the payload causes the payload to produce a diversionary acoustic effect.

A single use diversionary device having a semi-hollow barrel with a closed first end forming a pressure-resistant bulkhead and a second open end that receives one or more powder filled cartridge assemblies. A pivotable gate is mounted at the second open end of the barrel and configured to direct an explosion in more than one direction. A cap containing electronic delay circuitry is attached to the first closed end.
