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 stun grenade includes a cartridge having an explosive charge in communication with a fuse and a housing including a closed end, an open end, a longitudinal axis and including an internal cavity which accommodates the cartridge. An end cap is attachable to the open end of the housing, the end cap including an end wall and a side wall. A plurality of spaced first vents are defined in the end wall of the end cap. A plurality of spaced second vents is defined in an end wall of the housing. The output from an explosive charge is optimized by vents having a straight flow path. The vents have a first end in fluid communication with the cavity and a second end in fluid communication with an exterior periphery of the housing.

A selectable yield fragmentation grenade is provided with a feature for relatively easily setting the output of the grenade to a higher or to a lower yield lethality output of fragments. An operator can selectively inflate the grenade by various provisions, and such inflation lowers the grenade's lethality yield output.

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 rupturable bag assembly including a balloon, an outer wall, an inlet port, and a heat resistant shield. The balloon is fabricated from an elastic material. The outer wall is disposed around the balloon, the outer wall having a perimeter seam which parts abruptly at a predetermined tension. The inlet port passes through the outer wall into the balloon for inflating the balloon to produce the predetermined tension. The heat resistant shield is disposed within the balloon opposite the inlet port. The outer wall is constructed of a relatively inelastic material in comparison to the material used to construct the balloon. There is a dispersible medium disposed within the outer wall and/or the balloon.

A hand-throwable effect-producing body with a manually graspable housing body, a manually operable triggering device having a spring-loaded impact body, an ignition device initiatable by the triggering device and comprises an ignition charge, a delay device is initiatable by the ignition device and comprises a delay charge and a delay line, and a main charge configured to be initiated directly or indirectly by the delay charge. The impact body is configured to be manually moved along the longitudinal axis thereof counter to a spring force into a preloaded position and to be releasably arrested there and to be released by manually operating a triggering element of the triggering device, such that it can shoot out of its preloaded position along the longitudinal axis against an axial stop and thereby initiate the ignition charge.
