Abstract: A door breach training system usable within the door opening of a training structure. The system comprises a door and a frame having a lunge jamb and a lock jamb. The hinge jamb is connected to the door with at least one hinge. The system has at least one mount-and-socket pair having a frame mount connected to the frame, a frame socket connected to the frame mount, a door mount connected to the door, and a door socket connected to the door. One or more pins may engage the mount-and-socket pairs to prevent the door from opening, which, during training, much be sheared or crushed.

Abstract: The present disclosure relates to an Improved Ballistic Chain Cutting Device. In general, the device positions a target link from a multi-link chain in the proper placement for a single shot from a firearm to cut or sever the target link. Embodiments of the improved device include a specially designed slot with stepped sidewalls creating a varying width to tightly receive the target link, a curved adjacent link engagement region to better accommodate the semicircular end of a link adjacent the target link, and a curved target link engagement region to better secure the target link within the device.

Abstract: A security door breach training system comprising a frame member; a plurality of elongate members, each of the elongate members fixed to the frame member and having a free end spaced from the frame member, the plurality of elongate members including at least one capture member, a first clevis member, and a second clevis member fixed to the frame member opposite the first clevis member; at least one retention bar attached between two of the elongate members and spaced a distance from the frame member; and at least one retaining pin adjacent to the frame member, the at least one retaining pin comprising an elongate element at least partially adjacent to the frame member and having a first end and an opposing second end, a retaining pin socket attached to the elongate element proximal to the first end, and a stub extending from the at least one elongate element proximal to the second end.

Abstract: A system and method for ballistically cutting a multi-link metal chain comprises a chain alignment module that comprises three pins and attaches to the barrel of a firearm. A first pin and a second pin of the module fit on opposite sides of a target link of the chain. A third pin of the alignment module goes through a link adjacent to the target link of the chain. The three pins align the target link so that a bullet exiting the barrel of a firearm impacts a semicircular region of the target link to cause the target link to open.

Abstract: A security door breach training system comprising a frame, a door attached to the frame, a latch attached to the door having a latching end, a plurality of elongate members fixed to the frame, at least one retaining pin adjacent to the frame and having a stub, a latch-receiving member positioned between the frame member and the stub of the at least one retaining pin, an elongate body having a first end attached to the third surface of the frame member and a free second end; and at least one bar attached between two of the elongate members.

Abstract: An explosive breach training system comprising a frame having a lock jamb with two opposing ends and an inner surface, first and second opposing frame members connected to the opposing ends of the lock jamb, and a third frame member having ends connected to the first and second frame members opposite of the lock jamb. The frame defines an interior space. A cylindrical elongate member is within the interior space and has ends attached to the first and second frame member at attachment points. A door member has a hinge side and a lock side, and is within a door space at least partially defined by the lock jamb and the portions of the first and second frame members extending between the attachment points and the opposing ends of the lock jamb. A lock bracket is adjacent to the lock jamb, and defines an elongate slot intersecting with a portion of the door space.

Abstract: An explosive breach training system comprising a frame having a lock jamb with two opposing ends and an inner surface, two wide members connected to said opposing ends of said lock jamb, and a long member having ends connected to said wide members opposite of said lock jamb. The frame defines an interior space. A hinge jamb assembly comprises an elongate member within the interior space, with the hinge jamb assembly being slidably attached to the frame and selectively moveable between said lock jamb and said long member. A door member has a hinge side attachable to said hinge jamb assembly and a lock side, and is sized to fit in a door space defined by the elongate member, the lock jamb, and the portions of the wide members extending between the hinge jamb assembly and the opposing ends of the lock jamb. A lock bracket is adjacent to the lock jamb, and defines an elongate slot intersecting with a portion of said door space.

Abstract: A door breach training system comprising a first restraint assembly connecting a door to a frame. The door is attached to a lock jamb of the frame with a first restraint assembly that exposes a shear joint to impact from a projectile, such as shotgun round. Another embodiment further comprises attachment of the door to the hinge jamb with at least one second restraint assembly that functionally simulates a typical door hinge and exposes a shear joint to impact from a ballistic round. The preferred embodiment includes replaceable lock panels and hinge panels that are designed to break in a known manner in order to replicate those same failure modes for both door locks and door hinges in typical residential and commercial construction environments.

Abstract: A packable battering ram quickly disassembled for transport by two or more persons. In the preferred embodiment, the invention has first and second body members that are symmetrical, but otherwise identically shaped and sized. When assembled, the first and second body members form a lower surface that has a concave portion that approximates the natural curvature of the back of an adult male. The packable battering may be disassembled to distribute the weight between multiple people, yet quickly assembled for use upon arrival at a emergency response location.
