Which two types of trajectory are identified in the Method of Engagement?

The correct answer identifies the two types of trajectory recognized in the Method of Engagement as low angle and high angle.

Low angle trajectory typically refers to a firing approach where the projectiles are launched at a relatively shallow angle, allowing them to cover more horizontal distance before reaching their target. This method generally facilitates target engagement over obstacles and is often used in direct fire engagements.

In contrast, high angle trajectory involves launching ammunition at a steeper angle. This approach is particularly useful for targeting objects that are directly behind cover or for fire missions that require hitting targets at high elevations. High angle trajectories are commonly associated with indirect fire, where the projectile may arc over obstacles to reach its destination.

Recognizing these two types of trajectories assists personnel in choosing the appropriate method to engage targets effectively based on terrain and target location. Understanding the implications of each trajectory type is vital for successful mission planning and execution in artillery and fire support operations.
