What is the maximum effective range of MK153 (SMAW) against HEAA?

• A. 400 meters
• B. 500 meters
• C. 600 meters
• D. 450 meters

Answer: (B)

The main idea here is understanding what “maximum effective range” means for a weapon against a specific warhead and target. For the MK153 SMAW used with the HEAA (High-Explosive Anti-Armor) warhead, effectiveness isn’t about how far the rocket can fly, but how far you can reliably defeat armor at a practical hit probability.

At about 500 meters, the SMAW with HEAA maintains enough energy, proper trajectory, and warhead performance to defeat typical armored or fortified targets under standard firing conditions. Beyond that distance, velocity, dispersion, and the warhead’s ability to penetrate armor degrade enough that your chances of a hit yielding the desired armor defeat drop significantly. That balance—maintaining reliable hit probability and armor defeat—defines the maximum effective range, which is why 500 meters is the correct choice.
