       | Do you really need to burn through steel plate? Seems like
       | something like this is for shooting down cheap drones.
       | 
       | Though I've always wondered about laser weapons -- I'd think the
       | obvious defense is cladding the device in a mirror surface.

           | If my dealings with (much, much) smaller lasers are an
           | indication, "regular" smoke from laser-heated things is
           | generally buoyant in air, and would tend to just float up and
           | away from a presumably-horizontal beam. It seems like this
           | would limit the smoke's abilities to diffuse and absorb the
           | energy.

           | Intumescent paint would do the trick.
           | 
           |  _Intumescent paints are considered the lightest form of
           | passive fire protection. An intumescent is a coating that,
           | when exposed to heat, is rapidly transformed through
           | sublimation, and expands many times its original thickness
           | (up to 100 times), to form a stable, carbonaceous char._
           | 
           |  _The resultant char reduces the conduction of heat from the
           | fire to the substrate, delaying the time it takes to reach
           | structural failure._
           | 
           | I'm considering getting some for my kitchen remodel.

       | Mobility to deployment, then defended asset which in turn offers
       | perimeter defence against unmanned subsonic directed or non
       | ballistic weapons. (I'm guessing supersonic and ballistic bring
       | different problems)
