A weapon may comprise an explosive charge, an activatable detonation ignition means, an activatable deflagration ignition means, and an ignition device. The ignition device can activate, selectively, the detonation ignition means or the deflagration ignition means. The activated detonation ignition means can cause the explosive charge to detonate. The activated deflagration ignition means can cause the explosive charge to deflagrate. According to one method, the ignition device activates the detonation ignition means, which causes the explosive charge to detonate. If a predetermined event takes place without the explosive charge detonating, the ignition device activates the deflagration ignition means, which causes the explosive charge to deflagrate.

A battlefield weapon system is proposed to counter the threat posed by small drones. The system uses a standard .50 caliber machine gun firing explosive rounds, to create a flak bombardment to bring down the drone. A control system causes the round to fragment as it approaches the range of the target. The direction in which the round is fired is controlled manually by the gunner. The system is fully portable for dispersed deployment among infantry.

Disclosed herein is a payload delivery device. The payload delivery device is configured for delivering an explosive component. The payload delivery device comprises a first module having an interior cavity for containing an explosive component. The payload delivery device further comprises at least one attachment module connected to the central module via a connection means. The at least one attachment module having an interior cavity for containing an additional component.

A system for neutralizing a biological organism is provided. The system includes a first element is made from paraformaldehyde. A second element is configured to generate heat and decompose the paraformaldehyde into formaldehyde gas. In one embodiment, the second element is configured to have an exothermic and self-sustaining alloying reaction in response to being thermally energized by an initiator.
