Which weapon has grazing fire listed as N/A?

• A. M240B
• B. M2 .50 Cal
• C. M224 mortar
• D. MK19

Answer: (D)

Grazing fire is the direct-fire path where rounds skim close to the ground, staying at a very low elevation to sweep a strip of terrain. The M240B and M2 .50 cal are capable of delivering a near-ground trajectory when fired at low elevations, so grazing fire is a meaningful and attainable concept for them. Mortars, being indirect-fire weapons, rely on high-arcing trajectories and aren’t used to skimming the surface, so grazing fire doesn’t apply. The MK19, a 40mm grenade launcher, fires ammunition whose ballistic path is not suited to a true ground-skimming trajectory; its rounds arc and explode above ground, making grazing fire not applicable. That’s why grazing fire is listed as N/A for the MK19.
