Which weapon has a maximum effective range of 1,829 meters when used on a tripod?

• A. M240B
• B. M32A1 MSGL
• C. M27 IAR
• D. MK-19 Mod 3 Automatic Grenade Launcher

Answer: (D)

The key idea is that long-range effectiveness for these weapons depends on how they fire: indirect-fire grenades launched from a tripod can reach farther than direct-fire small arms. The MK-19 Mod 3 Automatic Grenade Launcher fires 40mm grenades and, when mounted on a fixed tripod, is stabilized enough to engage area targets at about 1.8 kilometers. That puts the maximum effective range near 1,829 meters, making it the weapon best suited to that range. The M240B is a belt-fed machine gun whose effective range for typical direct-fire targets is shorter, the M32A1 MSGL is a grenade launcher with a shorter practical range than the MK-19, and the M27 IAR is a 5.56mm rifle with a much shorter effective range. So the tripod-mounted MK-19 fits the given range best.
