Abstract: A warhead has a pair of shells, each having an annular rim at one end and opening at the other end. The rims abut one another and are fastened together to define a chamber filled with explosive having a bore aligned with the openings. The explosive has sensitivity to detonation that requires axial detonation in the bore by a detonating cord to initiate explosion thereby preventing detonation by lesser stimuli. A tube extends through the openings and bore and is sized to receive the detonating cord. Opposite ends of the tube are crimped to hold the shells together. A line charge provided with a plurality of such warheads has significant pressure, shock, fragmentation energy, wire cutting ability and mine neutralization capacity as compared to contemporary devices. These improved capabilities are directly attributed to the explosive type and density of this design.

Abstract: A reusable gas-powered war game land mine has at least one launch tube with ne or more projectile(s) loaded therein. A compressed gas reservoir and rupturing device are provided with the rupturing device being movable in relationship to the seal of the compressed gas reservoir. A triggering mechanism is coupled to the rupturing device to move the rupturing device so that it impacts the seal when the triggering mechanism is activated. The rupturing device can define a channel through which the compressed gas is directed to the breech end of the launch tube(s) when the seal is broken. As a result, the compressed gas enters the breech end of the launch tube(s) to propel the projectile(s) therefrom.
