Mobile UAV would be like glider that arcs up to about 200m and continues in a straight line until shot down, hits a border (and just stays there, pushing unable to move forward), or runs its course (1000m)
Decoy would be a targetable rumbling heat generator. It would be a tiny device (think NARC-sized) that would be lob-able to a distance and would show up by radar, heat vision (emit heat) and bounce around in place to trigger seismic.
