By the way, the military trackers are remarkable because they bring the aesthetics of the “Star Wars” into real life: NATO countries predominantly use tracing bullets with magnesium, giving a bright red flame (as in insurgent rebels); and the USSR and other Warsaw Treaty countries until a certain point used bullets with barium salts, giving a green mark (as in the star of the Galactic Empire). On the other hand, laser swords are usually painted in reverse (red in bad, green and blue in good). Go guess it.
