An example barrier can be switchable between an at least partially collapsed state and at least partially expanded state (e.g., a deployed state). For example, the barrier can be formed from a sheet and a plurality of rigid sections (e.g., rigid panels) attached or incorporated into the sheet. The barrier can also include a plurality of hinges, such as hinge lines, between the panels that are formed from the sheet. The hinges enable the barrier to be rigid foldable (e.g., the hinges can fold and unfold while the rigid sections remain stiff and rigid) between the expanded and collapsed states.

A ballistic breacher shield has a combined shield/battering ram functionality. The breacher shield's design permits an officer assigned to breach a barrier (such as a door) to have shield protection as he approaches the barrier, a battering ram to break open the barrier, and then the shield protection again once the barrier has been breached. The officer's follow-through for breaching a door positions the breacher shield to provide cover for the entire team lined up in a stack for entering the barricaded dwelling. The breacher shield has a flattened top to provide a greater area of impact for battering and a shape/size to act as a shield. The sizes of the shields may vary to accommodate individual preference and/or the size of operator. Shields are suitable for right-handed or left-handed operators, and may have an agency identifier and/or lights used for illumination or red and blue flashing lights for use as identifiers and attention attractors.

An Anti-Ballistic chair having a back portion, a seat portion, and an Anti-Ballistic panel within at least one of the back portion, and the seat portion, wherein the Anti-Ballistic portion comprises at least a first layer of Anti-Ballistic material formed from high-strength synthetic fibers extending in a first direction, and at least a second layer of Anti-Ballistic material formed from high-strength synthetic fibers extending in a second direction, different from the first direction.

The invention relates to a protective shield that can be worn by one person. This shield encloses this person's entire upper body and is made of bullet-resistant or fragment-resistant material. The protection shield consists of two concentric hollow semi-cylindrical or conical halves. The first half has slightly smaller outer dimensions than the second half and includes belts or straps, such that the wearer can carry this first half on his back like a backpack. The second larger half is rotatably mounted on the outside of this first half and can hold 180 rotated degrees about a vertical axis of rotation. The protection shield can also include more than two concentric hollow semi-cylindrical or conical halves.

A ball turret includes a turret shell having a rear portion and a front portion. The rear portion and the front portion are assembled to form the turret shell. The shell includes a block assembly configured to mount to a mounting element of a weapon system, and a yoke carriage assembly configured to receive and mount to the block assembly. A number of guide rods within the turret shell are configured to mount the yoke carriage assembly thereto and to provide a recoil shock absorber in response to a discharge of the weapon system. The yoke carriage assembly is releasably mounted to the block assembly.

A multi-layer body armor plate includes a strike plate; a mesh layer positioned over the strike plate, the mesh layer having a number of open cells; and an outer skin layer positioned over the mesh layer so as to encapsulate the open cells of the mesh layer between the strike plate and the outer skin layer. The open cells of the mesh layer may entrap air or may be filled with expandable, buoyant foam.
