The present disclosure provides a throwing device with a launcher and a propulsion system. The propulsion system comprises a retardant set between two sections of propellant for delaying the combustion and reducing the generated smoke or heat while launching the propulsion system. The launcher comprises: a tube for containing the propulsion system; and a trigger for triggering the ignition cartridge. A screw hole is in center of a bottom of the first chamber; nozzles are located around the screw hole; and a collar with a hole fixed in the bottom of the first chamber, wherein the ignition cartridge is fixed in the screw hole by the collar. The ignition cartridge comprises an explosive primer, and the launcher further comprises a firing pin triggered by the trigger to hit the explosive primer.

A squib assembly for a non-electric initiator of an anti-personnel obstacle breaching system includes a housing configured to connect to the igniter of a rocket motor of the anti-personnel obstacle breaching system, a slider assembly slidably contained within the housing and configured to connect to a shock tube of the non-electric initiator, and a pyrotechnic element disposed within the housing. Upon activation of the non-electric initiator, the squib assembly is configured to mechanically puncture a base of a initiator sleeve of the rocket motor and to thermally initiate ignition of the rocket motor.

The invention relates to an igniter with a delay time (Vz) that can be set. The delay time (Vz) can be fixedly defined, or individually and situation-dependently set on-site. In particular, the invention relates to a delay time that can be set for a stun grenade, a hand grenade etc., with options for the individual setting and situation-dependent or situation-contingent customisation of the delay time (Vz), and consequently of the effect of the active compositions in-situ. In order to achieve individual setting options, the invention proposes that at least two different delay times (Vz) can be set. To this end, the igniter has, in a delay section, preferably in the fuse head, a relief bore that can be closed or opened.
