A breaching device includes a body having a tamping material. The body has a target surface that is configured to face a target to be breached and a backing surface that is opposite the target surface. The tamping material is formed of gel and is configured to reflect an explosive force directed way from the target surface towards the target surface.

A wall for a building that includes a framed wall structure including a top support, a bottom support, and opposing side supports connected together, and at least one intermediate support attached to the top support and the bottom support, and a blast panel made of a cementitious material attached to the framed wall structure.

A munition includes a warhead having a warhead axis and axially opposed first and second warhead ends. The warhead includes: a tubular shock attenuation barrier including an axially extending passage extending from a first barrier end proximate the first warhead end to a second barrier end proximate the second warhead end; an explosive core charge disposed in the passage; an explosive main charge surrounding the shock attenuation barrier; projectiles surrounding the main charge; a core charge detonator; and a main charge detonator. The warhead is configured to be activated in each of a first projection mode and an alternative second projection mode. When the warhead is activated in the first projection mode, the main charge detonator detonates the main charge to thereby forcibly project the projectiles from the warhead with a first set of projection velocities and velocity profile. When the warhead is activated in the second projection mode, the core charge detonator detonates the core charge proximate the first barrier end such that a core charge detonation wave propagates through the passage to the second barrier end and, at the second barrier end, the core charge detonation wave detonates the main charge to thereby forcibly project the projectiles from the warhead with a second set of projection velocities and velocity profile. The second set of projectile velocities and velocity profile is different from the first set of projectile velocities and velocity profile.

A device for destroying a chemical agent is described. The device includes a self-contained, portable pressure vessel which is dimensioned to accommodate an artillery shell, and a heat-generating component within the pressure vessel. The heat-generating component is capable of providing a pyrolytic, exothermic reaction capable of destroying the chemical agent and artillery shell. A process for destroying a chemical agent which includes placing a chemical artillery shell within the pressure vessel, securing the pressure vessel closed, and igniting the heat-generating component inside the pressure vessel to generate a pyrolytic, exothermic reaction capable of destroying the chemical agent and artillery shell is also described.
