What is the maximum effective range of the M136 (AT4)?

• A. 200m
• B. 300m
• C. 350m
• D. 400m

Answer: (B)

Maximum effective range is the distance at which you can reliably hit and affect a target with the weapon under normal conditions. The M136 AT4 is a disposable, unguided rocket that flies on a ballistic path and has no guidance system. Because it lacks guidance and must rely on a fixed trajectory, accuracy and energy delivery drop as range increases. Its warhead is designed to be effective up to about 300 meters, so beyond that distance the chances of a hit with meaningful damage become too low for practical use in standard engagements. The rocket can travel farther, but reliability and lethality diminish past roughly 300 meters, which is why that distance is considered its practical maximum.
