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.

A method and system for generating tactical routes includes an intervisibility database pre-populated with pre-computed optical lines of sight between locations or nodes in geographic terrain, an intervisibility analyzer for analyzing propagation of the pre-computed optical lines of sight between the locations or nodes in the geographic terrain, a speed analyzer for analyzing speeds of travelers across the locations or nodes in the geographic terrain, a cost generator for generating a blended cost grid using said intervisibility and speed analyses, and a route generator for generating routes that facilitate tactical movement based on said blended cost grid. The route generator computes intervisibility unions at the locations or nodes in the geographic terrain and minimizing intervisibility unions along the generated route.

A method comprising the steps of propagating an infrared laser pulse in air, self-focusing the laser pulse until the laser reaches a critical power density, wherein molecules in the air ionize and simultaneously absorb a plurality of infrared photons resulting in a clamping effect on the intensity of the pulse, wherein the laser pulse defocuses and plasma is created, causing a dynamical competition between the self-focusing of the laser pulse and the defocusing effect due to the created plasma, the laser pulse maintaining a small beam diameter and high peak intensity over large distances, creating a plasma column, repeating the above steps to create a plurality of plasma columns, creating a parallel linear array with the plurality of plasma columns, and using the array to deflect an incident energy.
