Linear and rectangular targets require orientation in terms of direction. The observer must send target description, length, width, and what else in the third transmission of the call for fire?

In the context of a call for fire involving linear and rectangular targets, the third transmission requires the observer to provide comprehensive details that facilitate accurate targeting. The inclusion of elevation is critical because it provides the necessary vertical reference point to ensure that the munitions are effectively aimed at the target height, which enhances the precision of the engagement.

Elevation aids in addressing vertical differences in terrain, ensuring that the artillery fire can be accurately delivered to meet the specific requirements of attacking either linear or rectangular targets. This information allows the fire control team to calculate the appropriate firing solution, taking into account the trajectory of the artillery round and the established target parameters. The mention of elevation contributes significantly to the overall success of the mission by minimizing the risk of overshooting or undershooting the target.

Without this vital piece of information, the effectiveness of the artillery strike may be compromised, leading to potential inaccuracies in neutralizing the intended target.
