A helmet attachment system is usable to attach a mandible or face or mouth guard. The helmet attachment system also comprises a pair of attachment bases, each arranged on a side of the helmet near to an ear covering of the helmet. The attachment bases each include a metal base plate covered by an attached body block. Each attachment base provides provisions for attaching opposite ends of a mandible to the bases. The metal base plate includes hooks for engaging an edge of the helmet. A pair of strap assemblies is provided, each strap assembly connected to one attachment base. The strap assemblies extend rearward and are connected to the back rail by a buckle member on the end of each strap assembly. The back rail includes a pair of buckle member-receiving slots. The straps assemblies and the hooks provided on the attachment bases secure the attachment bases to the helmet.

An integrated airspace defense system for identifying and locating a suspicious unmanned aerial vehicle. The system including at least one detection device to monitor the air space and provide a detection information; a computer to process the detection information and identifying the presence of suspicious unmanned aerial vehicles (UAVs) using a sequence of detection algorithms. The integrated airspace defense system identifies and locates the suspicious UAV. In at least one embodiment the integrated airspace defense system is capable of capturing or destroying the suspicious UAV.

A capture drone is an unmanned flying object that flies in the air. The capture drone includes a capture net that captures other object in the air, a weight capture determining unit that detects that the capture net has captured the object, and an autonomous flight controller that controls a flight state of the capture drone to be an autonomous flight state not dependent on an operation signal from the outside if the weight capture determining unit detects the capture of the object.

There is disclosed a line apparatus for inhibiting an airborne target. The line apparatus comprises at least one line comprising: a flexible tubular member, having a wall and defining a bore; and a fluid adhesive housed within the flexible tubular member, wherein the flexible tubular member is configured to express the fluid adhesive through the wall.

A system for defeating a threat unmanned aerial vehicle. The system includes a friendly unmanned aerial vehicle, a capturing device configured to be suspended from the friendly unmanned aerial vehicle for arresting a threat unmanned aerial vehicle, and one or more load-limited release mechanisms for removably suspending a releasable portion of the capturing device from the friendly unmanned aerial vehicle. In certain embodiments, the load-limited release mechanisms are configured to release the entirety of the capturing device from the friendly unmanned aerial vehicle upon capture of the threat unmanned aerial vehicle. In other embodiments, the load limited release mechanisms are configured to release only a peripheral portion of the capturing device to reposition a captured unmanned aerial vehicle to a central portion of the capturing device for carrying the captured vehicle to a remote location.
