What is referred to as the horizontal range?

The term "horizontal range" specifically refers to the distance between the gun and the point of impact on the ground, measured in a straight line. This concept is crucial in ballistics and artillery, as it helps to determine how far a projectile will travel before hitting the target. It takes into account factors such as the angle of fire and the initial velocity of the projectile, ultimately enabling effective targeting and engagement.

In contrast, elevation height pertains to the angle at which the gun is aimed but does not directly represent how far the projectile travels horizontally. The total distance covered during flight includes both the horizontal and vertical components of the projectile's trajectory, which goes beyond simply measuring the horizontal range. The vertical distance from the starting point would imply a measurement of altitude or height rather than the horizontal distance traveled. Thus, defining horizontal range as the distance from the gun to the point of impact is both precise and aligned with established terminology in the field of fire control and ballistics.
