How high above ground does a NSB engage?

The NSB, or Non-Standardized Base, refers to the height at which a mortar system engages when firing. Engaging at a height of 1 meter above the ground allows for a balance between effective targeting and minimizing the risk of deflection or loss of effectiveness due to proximity to the terrain. This height helps ensure the trajectory of the mortar round is optimized for accuracy and efficiency in hitting the designated target.

The other options would typically represent heights beyond the standard engagement level for an NSB, which could introduce unnecessary complications in terms of aiming, trajectory calculations, or stability in engagement. At a height of 1 meter, the NSB can effectively utilize its design capabilities and deliver munitions accurately to intended targets while maintaining an adequate safety margin from the ground.
