USMC Infantry Rifleman (MOS 0311) Practice Test

Max range is determined by the weapon’s propulsion and design, since the M72 LAW is a disposable, single-shot anti-armor rocket. It fires an unguided 66-mm rocket, and the motor only provides thrust long enough for the round to travel about 1,000 meters. That published maximum range is why 1,000 meters is the correct answer. In practice, you’d engage targets well within that distance, as accuracy and stability drop toward the limit. The other distances either exceed the rocket’s flight envelope or aren’t the official maximum—for example, 1,200 meters would be beyond what the motor and aerodynamics reliably support, while 900 and 800 meters are shorter than the maximum.
