In which element would you request high angle when engaging mortars in defilade?

Requesting a high angle when engaging mortars in defilade is focused on the method of engagement. This element specifically deals with how the target will be engaged, including considerations like trajectory, angle, and type of fire that will be used.

High-angle fire is necessary when dealing with targets that are protected from line of sight by terrain features, like defilade. This means the rounding angle of the projectile needs to be elevated to ensure it can reach targets that are obscured or protected by landscape features. Therefore, the method of engagement explicitly includes the details of how to achieve that high angle shot, making it the most relevant element for this scenario.

The other elements—method of preparation, method of fire, and method of target—do not directly address the specifics of the engagement technique required in this case. The method of preparation would cover how to ready the artillery piece, while the method of fire pertains to the technique of delivering the ordnance. The method of target might involve how the intended target is identified and categorized, but does not dictate the firing angle needed for engagement through defilade. Thus, focusing on the method of engagement is critical for successfully executing a high-angle mortar operation.
