In one embodiment, a safety trailer has semi-tractor hitches at both ends and a safety wall that is fixed to one side of the trailer. That side, however, can be changed to the right or left side of the road, depending on the end to which the truck attaches. A caboose can be attached at the end of the trailer opposite the tractor to provide additional lighting and impact protection. Optionally, the trailer can be equipped with overhead protection, lighting, ventilation, onboard hydraulics, compressors, generators and other equipment, as well as related fuel, water, storage and restroom facilities and other amenities.

Unmanned aerial vehicles and methods for providing the same are disclosed. The unmanned aerial vehicles may have various configurations related to a support frame. The unmanned aerial vehicles may have various configurations with a continuous track for ground propulsion. The unmanned aerial vehicles may have various configurations related to payload clamps.

Invention is an anti-mine pad for protecting legs against anti-personnel pressure-type mines. The pad comprises a rigid horizontal platform, support legs and footwear-fastening elements. The platform has an upper surface for footwear and a lower convex surface. The lower convex protrusion's vertex faces downwards. The platform's lower surface lacks parallel planes when projecting a human foot relative to the upper surface. The support legs provide a space between the platform and the ground. Contact points between the support legs and the ground are outside the platform. The arrangement height of the platform's upper surface above the ground is 40-99 mm. Rigid polymeric material of the pad's inner frame has a greater rigidity than an outer shell's material. The pad protects the human foot against explosions of the anti-personnel pressure-type mines, has small weight, dimensions, is convenient for transportation, easily taken off/worn and reliably hold the user on a surface.
