Which statement correctly describes the maximum ranges and tracer burnout values shared by GAU-18A and GAU-21?

• A. Maximum range 7,000 meters; tracer burnout 1,500 meters
• B. Maximum range 3,000 meters; tracer burnout 750 meters
• C. Maximum range 5,000 meters; tracer burnout 2,000 meters
• D. Maximum range 7,000 meters; tracer burnout 750 meters

Answer: (A)

The main idea is understanding how far a round can travel and how long tracers stay visible. For these two Gatling-type guns, the specified maximum range is 7,000 meters, which is the farthest distance a round can reach under ideal ballistic conditions. The tracer burnout value of 1,500 meters means tracers remain visible only up to about 1.5 kilometers; beyond that distance the tracer flame stops, so you no longer see the tracer even though a ball round may continue beyond that point. So, the best description is that both guns share a maximum travel distance of 7,000 meters and tracers burn for about 1,500 meters, after which they cease to be visible. This reflects the combination of the projectile’s ballistic limits and the tracer material’s burn characteristics.
