What is the purpose of 'Sight Angle'?

'Sight Angle' specifically refers to the angle at which the gun barrel is elevated above the line of sight to the target. This elevation is critical in ballistics because it affects the trajectory of the projectile being fired. When aiming, the gunner must account for this angle to ensure the projectile reaches the target accurately, especially at varying ranges where the curvature of the projectile's path can significantly impact accuracy.

In practical terms, elevating the barrel allows for compensation for factors such as distance and the effects of gravity on the projectile’s flight. A proper understanding of the sight angle is essential for effective targeting and ensures the artillery or gun system operates with precision.
