There is interest in how a self destructive nuclear weapon can warn troops. You cannot let it off until you know there has been a launch. Then you need a large visible mushroom sent straight up into the air a little higher than usual. For example a 10mt between Iraqi bases without serious burns or burns. The idea is to fake an attack on a neighbouring base, in that direction. There is a possible five minutes drive time, perhaps more. Five minutes open road is outer blast radius. Keep hair gel with you & a spare beret.
