I have watched the movie "Soldier Assault" and wanted to know why the body smoked after being shot during the exercise.

The chimney can start emitting smoke when illuminated by enemy lasers. At this time, the person or equipment is judged to have been hit by the enemy and exits the exercise. The laser receiving devices on different personnel and equipment are different, and they can only start smoke at a set intensity. Lest a rifle's laser cause the enemy tank to smoke, causing a "rifle destroys the tank" joke. In addition, some large-scale equipment and tactics are not suitable for air combat with the above-mentioned devices, such as missiles and aircraft. The neutral exercise command will determine the outcome based on the on-site combat conditions. Both parties involved in the exercise must accept its judgment unconditionally.
